when I chose an item in a right click menu it stuck on screen,
It dissappeared when I locked and then unlocked the pc,
but reappeared the next time I selected an item. This does not work in windows 7 (and maybe 8), the quick workaround there is Start > Run :
tskill dwm
Right clicking the desktop and closing the menu also helped, but this were only workarounds.
I finally solved it :
Go into Windows Performance Options and de-select the option for "Fade out menu items after clicking."
In Vista, you can find it by right clicking My Computer > Properties > Advanced system settings (link on the left) > Advanced (tab) > Performance settings (button) > Visual effects (tab).
To cure it one in windows 7 you can set the corresponding monitor from 32 bit to 16 bit and back again, to remove one item. If it keeps happening, use the above solution.
