Right click menus are transparent

A few hours ago, my right-click menus in all the different tasks have disappeared. Actually they have sort of gone transparent. When I right-click an icon all I get is the shaded frame of what should have been a menu. but within it you see the active window.

If I hover with the mouse pointer over where the menu should have appeared, then the different menu items will show up one after the other, as I pass their location with the pointer.

Any ideas?

Thanks,

roypeled--I have not experienced your problem, but since it is recent, you may consider trying a System Restore to a date before the problem began.
A possible reason for the problem could be some software/hardware change made recently.
