This might happen after the program is shut down and restarted. After resizing the the SeaMonkey window to become smaller, the menu bar becomes functional again! This problem may not be easily repeatable, but this jam has occurred couple of times with this new version 2.0.4! Reproducible: Sometimes Steps to Reproduce: 1.Maximize the Seamonkey window and shut down the system. 2.Start the program again! 3.If jammed resize the SeaMonkey window again, and the menu bar should work! Actual Results: May happen or not! Expected Results: The menu bar should not get jammed in any situation! This problem may not be easily repeatable, but this jam has occurred couple of times with this new version 2.0.4!
I haven't seen this with maximized windows but I can confirm that it happens in Firefox if the browser is closed while some windows are minimized. When reopened, the windows that were minimized are displayed normally but their menus don't work. I have a fix for this & several related problems. When I post it, I'll mark this bug as a duplicate of the new one.
Please see bug 561273 for a possible fix.
