I recently wrote about (P2984) the problems I've been having with Firefox on OS X. It has since turned out what's causing it. It's the Codetek Virtual Desktop Manager. As soon as it's active (I constantly have lots of windows open and otherwise can't find anything in the mess - and no, Expose wouldn't really help either), both Firefox and Thunderbird exhibit various misbehaviors:
- after startup the menu is empty. You first have to click in the background and then back on the application window for the menu to work properly
- the keyboard focus isn't always correct. Then you have to do the same as with the missing menu.
- after switching desktops (or also when normally hiding and showing the application again) the window is completely empty - only resizing it brings the content back.
As I said, this only happens with the desktop manager. Unfortunately I can't use Expose because I don't have 10.3. Besides, it wouldn't solve my problem: I need many parallel workspaces in which I have all the windows open for the respective task. Expose would only handle that very inadequately.
Bummer.
