Tested with 2002070904 WinXP classic theme 1 go to any site with rollover images, for instance http://www.netscape.com/ which as a menu on the left made up fo rollover icons. 2 Put your mouse pointer over the rollover links to have the "on" images loaded in memory 3 move your mouse over the rollover links, note that the throbber is spinning, the progress bar moving and the stop button flashing on and off. Expected result : There should be no activity since images are already in cache Actual result : the browser acts as if it were downloading the images (it is not, I also tested it offline) This is a regression bug but I could not tell wheter it is recent or not (I mainly browse text sites), NS7b1 does not have the problem though.

similar: bug 159701. I think there are more of these filed.

Another example: 1. Go to http://www.overture.com/ 2. Mouseover Overture Worldwide to the top right. Moving the cursor of the menu causes the stop button going on and off. Using build 20020723, Windows 98. Also seing this on Mac OS 9.

WFM with trunk 2002072718 on Windows Me. The mouseover images are (down)loaded properly. Though the menu at http://www.overture.com/ itself flickers and I couldn't find mouseover images at http://www.netscape.com/ I think http://www.hamtaro.com/home.html (which also WFM) is a better test URL since it has much more menu items and doesn't use them in a popup. Perhaps you move too quickly to let the mouseover image finish downloading?

wfm with win2k build 20020724..

Menu on this site makes the stop button flicker: http://www.hamtaro.com/home.html Using latest build 20020728 on Windows 98. Same on Mac OS 9.

One last url to show the problem: http://www.mercuriovalpo.cl/ Mouseover the menu to the left.

-> Imagelib

Works for me now with build 20020918, Windows 98.

No flickering anymore at http://www.mercuriovalpo.cl/ and http://www.hamtaro.com/home.html with trunk 2002101308 but the progress bar does go full and stays like that.

on earlier releases, i think 1.0, this bug would occur whenever the page had been reloaded, but not when the page was loaded the first time. even just hitting enter again in the location bar was sufficient to make the cached images work correctly. on 1.2b though, the bug occurs every time that i can see. check the logs, and you'll see all the unnecessary 304's to the page everytime you roll on and out. this bug caused a great deal of frustration to me when our QA department insisted that our website not 'flicker' in netscape 6... grr

"mass" re-assigning of bugs from pav to myself

updating target milestone

I can no longer produce any of the issues with mozilla 1.3 on win2k. I tried www.netscape.com, www.hamtaro.com/home.html (the progress bar is now ok), http://www.mercuriovalpo.cl/ or www.overture.com If anyone is still seeing rollover's causing requests, please let me know, otherwise... we can probably close this one.

Using Mozilla 1.3 & ngrep (to monitor network traffic), I was not seeing mouse overs generating any network traffic. Since this was fixed at somepoint, am marking fixed. If another occurence shows up, just re-open with new url.

Well, I don't see the simptoms on 20030305/linux, but the bug wasn't about network activity, it was about the stop button and throbber acting like there was network activity (which there wasn't).
