Hi, [This comment is a bit long. For those in a hurry, perhaps just read the "important part" set off below. :) ]
As with Dave Russell (comment #15), menus disappear for me constantly as well, both in Firefox and in Thunderbird. I'd say 20+ times an hour rather than 20+ per day. Globalmenus work OK, but right-click and dropdown menus disappear all the time, by either flashing incredibly briefly and then disappearing or sometimes appearing but then disappear as soon as I move the mouse (oddly, using up/down arrow keys does work correctly in this latter case). As with Domingos86 (comment #4), pressing Alt-Tab does seem to correct the problem. Unfortunately, unlike Dave (comment #15), unmaximizing then re-maximizing the effected window does _not_ work for me. ----- BEGIN IMPORTANT PART ----- POSSIBLY IMPORTANT: Unlike Domingos86 (comment #15), best I can tell, I seem to _only_ have the problem when using either the workspace switcher (I use this rarely) or pressing my middle mouse button, which I have mapped to invoke the same Expo view (within the Compiz Expo plugin; I use this constantly). On the other hand, when using the 4 Ctrl+Alt+<arrow key> combinations, I have yet to observe the menus / dropdowns disappearing (I will certainly pay close attention to this and report back if I observe otherwise). THUS, it might be that the initiation of the problem is localized to activating the Expo view (by whatever means) and then switching to a workspace with a Firefox / Thunderbird window. SO, I'm quite curious: Does anyone else besides Domingos86 encounter the problem _without_ going into Expo view shortly beforehand? ----- END IMPORTANT PART ----- I personally keep only one maximized window, Firefox, on workspace 2 and only one maximized window, Thunderbird, on workspace 4. I say this to say: I wonder if another limiting factor might be that the Firefox / Thunderbird window has to be maximized and the topmost (i.e., top of the window z-order) for the problem to occur. Has anyone encountered this problem with Firefox / Thunderbird _not_ being maximized?
