from Bugzilla Bug 58848 Click Excel Hyperlink, N6 loads it twice in separate windows. Click on a HyperLink in Excel. If N6 is already running, it loads web page twice, in separate windows. If it is not running, it launches, loads the web page in one window, and the home page in another. The first time I tried this, N6 crashed, but appeared to remain running, as if there were two instances of the app running, one of which crashed. This would also explain why I saw two Java icons in the Win98 taskbar on some tries. ------- Additional Comments From Bill Law 2001-06-01 16:16 ------- I looked into this a little bit. We are getting *two* requests from excel/word (I tested using an MS Word document link). I don't know why. Will take at least 1 day to figure it out. ------- Additional Comments From Bill Law 2001-06-12 16:41 ------- I investigated this a bit over the last couple of days. Clicking on a http: link in a Word document (I presume Excel does the same) generates two invocations of Mozilla: 1. The one registered under the http protocol. 2. The one registered under the .html file extension (this might differ based on the extension of the link). The tricky thing is knowing what the heck Word is thinking when it's doing this. It has something to do with DDE, because if I clear out the ddeexec subkey under HKCR/http/shell/open, then we only get 1 request (the one registered under http). It seems that the presence of the ddeexec entry causes Word to then issue a second request based in the file extension in the URL. The funny thing is that it doesn't seem to actually do any DDE. So a fix may be hard. I am working to completely remove our so-called support for these ddeexec subkeys. That's a little tricky because we can't just ignore them; other applications (i.e., Communicator or IE) will have already set these so we have to force them to be blank. There's also the interaction between those keys and integration with Explorer (i.e, dbl-clicking Internet shortcuts on the desktop). I have to go see if removing this degrades our support for that. Ideally, taking this step will also fix the problems related to that (e.g., bug 58770). ------- Additional Comments From Nick Hansen 2001-06-22 11:23 ------- Using the 2001062004 build of Moz as well as the N6.1beta under Win2K results in the following when there is no browser currently open and a link is clicked: 2. Word/Excel/Outlook opens two browsers, the first loads the page & the second remains blank but obscures the first browser window that actually loads the URL. ------- Additional Comments From Nick Hansen 2001-06-22 11:41 ------- I installed N6.1beta this nutty behavior changed. At that point, when I clicked a link in Outlook, it only opened one browser (N6.1b) but also put up a dialog asking me to locate the program used to open/handle this link (loose paraphrase). It replicated this behavior upon successive attempts until I helped Outlook locate the appropriate application (N6.1b). After doing this, it now opens two browser windows, etc. . . ------- Additional Comments From Frank Burleigh 2001-06-26 14:03 ------- *two* browser windows open in Word 2000, in Excel 2000 and in Outlook 2000.

paw able to repro this on his w2k machine with an office 2000 [he'll comment with details here soon]. cc'ing lisa as well.

ack, forgot to reaasign, since bill is away.

[sheesh, i keep forgetting to add comments at the right time...] as i had mentioned in bug 88086, i wonder if this might also be an issue on the Mac... or, relevant?

Thanks for tackling this, sairuh@netscape.com; hopefully these moves will get this on the radar again. Perhaps you could solicit the newsgroups for Mac testers? I am close to the support people in our building of several hundred NS4 users, and would say simply that the browser must behave in line with user expectations; any behavior short of that (opening two windows or IE) prevents us from deploying the browser, with all that implies. I know, I've tried. ;-) Thanks to you and to timeless.

zach is checking to see if he can repro this on his Mac OS X system [which has Office 2001 --not sure if/how that'd matter here, but couldn't hurt to check]. also cc'ing mpt and lordpixel to see if they might have access to Office apps, and hence see if they run into this bug. [if not, apologies for the spam.]

Works correctly for me (launches one browser window only) with Mac OS 9.1, Moz build 2001062708 and Word 98. Don't have Office 2001:mac...

I'm seeing this exact problem on my Win98SE system. Eudora behaves the same way, too. (which makes me see this bug every day) I've had Mozilla set up to handle HTML files , URLs, etc.. for quite a long time. Perhaps there is something wrong in the URL: HyperText Transport Protocol settings? In particular, the "DDE Application Not Running" section? I'm saying this because if Mozilla isn't running at all on my system and I click a URL in Eudora, 2 Mozilla browser windows are opened. If Mozilla is currently running, then it will just open one new window as expected. Just a guess...

Is this not a dupe of bug 59078 ?

*** This bug has been marked as a duplicate of 59078 ***

timeless didn't seem to think so. I don't believe it is unless you believe the behaviors have the same underlying cause. Bill Law Checked in stuff on another bug that improved this whole situation *but did not fix* Moz when run from links in MS Office apps. Also, I've found that by turning off DDE in my File Types dialog I can make Moz open once window when double clicking an HTML file in the file system.

i went to great effort to file these bugs seperately. if you want to accuse them of being dupes i expect you to run the qa to prove it to me. REOPEN.

Timeless, thanks for stepping back in. Do we (testers and administrators) need to do anything further (other than file Outlook 2k/XP as a separate issue)?

please try to provide the info i asked for in bug 88086 date: 2001-06-28 15:38. my impression was outlookxp behaved like office2k if that's the case it can live in this bug.

Ok, I will review bug 88086. Your impression is correct: Outlook XP and Outlook 2000 behave the same. In bug 88086 Blake Ross 2001-07-01 12:59 seemed to suggest filing a separate Outlook bug. I kinda want to hop a plane so we can all be in the same room, there's so much stuff around these. ;-)

I just wanted to report on similar experiences using Outlook 2000 on Win2k. However, when I click on a link in Outlook, it actually opens both in Mozilla and in IE. Clearing out the ddeexec subkey under HKCR/http/shell/open as described above fixed the problem, so I believe it is the same bug, however I do not know why it would open both Mozilla and IE (as opposed to two seperate Mozilla windows as everyone else is reporting). I don't believe I have changed any of my settings, aside from letting Mozilla set itself as the default for .html, http, etc. Will clearing out the ddeexec key screw up other programs though? Office programs, or things that rely on IE specifically?

Pchen - Are we gonna get to this one for eMojo? If so, please mark as nsbranch+.

I had to debug this at home, 'cause that's the only system I could find with Office2K. What I found was that Office2K (or the shell APIs it calls) will utilize the http protocol registry entries and invoke Mozilla. It will then (for some unknown reason) utilize the .html registry entries and launch Mozilla again. We can't tell this from two completely separate requests so we process both. While I don't know *why* we get the second request, I did figure out how to stop it. This is basically the same sort of thing I found for bug 58848. In that case, if the default value under shell/open/ddeexec existed, then the shell tried the .html route. With Office2K, it does that if there is *anything* under the shell/open/ddeexec subkey (e.g., empty Application or Topic subkeys). I can fix the problem by deleting the shell/open/ddeexec subkey in its entirety. I will be implementing code shortly that does that (rather than blank the dde subkey default values). But that code will come after I tweak the same code for bug 97813. I will have code early next week. See also my comments in bug 59078 (a similar problem reported on some Win2K system(s)).

Don't think Bill's fix will come in time for 0.9.4 ;-) Marking nsBranch and 0.9.5

nsbranch+, since you have a fix in mind that sounds simple. If that is not the case, I'd question the risk/benefit ratio of making such changes this late in the release.

Adding correctness Status Whiteboard, correct/expected behavior does not occur.

The patch that was promised for early in the week of 9/10 still hasn't shown up. PDT-. (It's too bad since it was supposedly a simple fix.)

->bill, since he was last working on it...but reassign if needed.

Generalizing summary to encompass all symptoms of this problem.

Resetting target milestone for all "window integration" bugs to mozilla0.9.8. I'm working on performance and won't get to that till next milestone.

Not getting to this, either.

Spam: Moving out bugs that there is no time for. Please note that some of these will hopefully be fixed in the course of fixing bug 59078. I just can't commit to fixing them all.

I have also had success (with 0.9.8) using DDE only. By removing the '-url' option from the end of the mozilla command line, but leaving the DDE to application 'IExplore', topic 'WWW_OpenURL'.

*** Bug 125224 has been marked as a duplicate of this bug. ***

I also noticed this bug, and I tried to change the settings for URL:http. I managed to get some improvements when I change the DDE Application from "IExplore" to "Mozilla". After the changes, clicking a link in another application correctly load the page in an existing Mozilla window, or launch Mozilla if it wasn't already opened.

You're almost there! I worked with that thing on my machine, and the following seems to fix it: Set ddeexec default value to -url "%1" (Quotes are important!) Set ddeexec/Application to Mozilla And voila - I can finally open links in Outlook

Last comment was made one year ago. Is this still an issue?

I haven't seen this problem in quite a while and I seem to remember it being fixed. I just tried the testcase and, with Mozilla open, it reuses the last used browser window as expected. I'd say it's FIXED or WFM.

Fixed ages ago.

marking worksforme based on comments (I can't test on win), please reopen if this is still an issue
