Status: RESOLVED DUPLICATE of bug 575864

(Thunderbird :: Toolbars and Tabs, defect)

Description

[geoff.letch]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.7) Gecko/20100713 Thunderbird/3.1.1

Every time I have opened Thunderbird 3.1.1 it has forgotten the last layout settings I have chosen.  For example, I select that I don't want the message pane displayed - and that I don't want the quick filter bar.  The next time I open the program it displays one or the other or both again!  Just like in previous versions, where the message pane would come back after an abnormal exit (for whatever reason) this settings "amnesia" happens almost every time I re-launch.

Reproducible: Sometimes

Steps to Reproduce:
1. Set layout to Message Pane unchecked
2. Set Quick Filter bar to unchecked
3. Re-start program 
Actual Results:  
Almost always, it forgets the way I have set things and comes up with it's own.

Expected Results:  
...for it to remember what I have selected - no matter how the program exited!

Was working quite well with version 3.0.5 - wha happen???
