This bugs bothers me since some time, but didn't had time to report yet. The problem: K Menu, context menus for the apps in taskbar, application launcher menu, etc. are not always clickable. In case of K Menu many times I may be able to navigate with the mouse, but after some time it stops, and I can't execute any application with the mouse, nor I can hide the menu with the mouse. The clicks are logged, as if I hide the menu with ESC, the application is executed (as many times as I clicked on the item). I can also execute the app with ENTER. 
Similar issue is with the context menus.
Might be related: in the quick launcher sometimes I click on an icon, the icon goes "down" but the app is not executed. I must click on it several times. And many times it happens that I must click several times to execute an application from the quick lanucher. And this is on an Athlon XP 2000+.
Although no data loss occures, I consider this a major bug.
