From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.9) Gecko/20020311 BuildID: 2002031104 The mail does not remember folder state when folder list is collapsed. Everytime that I want to see my inbox I have to open the folder list on the side fo the mail program and click on inbox. If I click to hide the folder list and then close the mail window the next time that I start the mail portion the message list area is blank. I cannot click get message. I have to click to open the folder list pane and then click on inbox to see my messages. If the folder list pane is left open then it will remember that I had clicked on inbox before closing. Reproducible: Always Steps to Reproduce: 1. Open mail 2. open folder list pane 3. click inbox 4. see messages in inbox 5. close folder pane 6. close mail portion 7. open mail 8. see nothing in message list area Actual Results: I did not see my mail messages on the start of the mail portion as I should have. Expected Results: The list of messages in my inbox should have appeared in the message list area. I am in windows 2000 sp2. I have tried this with and without netscape 6.2.1 installed. Heck, I even tried it on a clean install of win2k. Does the same thing everytime.

To my understanding the problem is that Mail is not opened in the default state - displaying Inbox content after Account level was collapsed and Mail closed.

This bug is much worse than stated, If you collape the left pane, exit mail, then come back, your presented with two completly blank panes. This is very confusing. I also had a report of someone who had reordered their subfolders, and suppositivly it loss the order upon them attempting to reproduce this bug. This effect also affects the addressbook too, if you close its left pane this is bug 136296 So basically the bug is that if there are folders on the left, and its contents on the right, even if there is a default folder, it won't be loaded if left pane is collapsed on load, I don't think this is mailnews specific.

Fix for this is to change in messenger.xul <vbox id="sidebar-box"> <vbox id="folderPaneBox"> This is what is done in the other 3 pane view (one where bottom window is wide), and it keeps the folder state. Apparently js code stats the a sidebar-box doesn't need to be preloaded till its opened. Obviously a folderpanebox would. Assume the fix for addressbook is simular will look into! :)

Ok that should be <vbox id="folderPaneBox" persist="width"> as its not remembering the width you set. Its also setting the default width to something a bit too small in addressbook and a bit too large in mailnews. It appears as though sidebar-box did this better, though I can't figure out how? any ideas?

we can't just change id's like that, and besides, changing sidebar-box to folderpanebox would break sidebar.

The window is unusable with no messages in the message pane and the workaround (opening the folder pane and then selecting a folder) is not obvious.

we'd need this fixed if we really wanted to support two pane mode. see other [twopane] bugs.

See discussion and patches in bug 123719.

The only remaining problem I see is that when the address book pane is originally collapsed then the personal address book isn't selected when you uncollapse it.
