Windows XP forum: Why Can't I right click my Desktop Icons???????????????

I have a Windows XP right click problem that's driving me insane--I right click any icon on my desktop (not limited to just my
Desktop, but it's where I first noticed this problem) and I get this Windows Explorer error message that states Windows Explorer has "encountered a problem and needs to close" (Error Signature below) --I have no choice but to hit the "Close" button--then when I do this, my desktop goes blank (black)for a second and then comes back (almost like it going to reboot but doesn't). What's really weird though is that if I right click just the background of my desktop (not pointing to any particular icon) the right click appears to function properly... Again, I don't have to be on my desktop for this right click problem to occur....

Does anyone have any idea how to fix this? I'm to the point I want to tear my hair out (didn't I already say that? Yes, I did--see this is driving me nuts!) I can't delete anything from my desk top, I can't right click on any object to find out "Properties" etc etc etc

I've already checked for things like the Sasser virus...

Any help would be greatly appreciated I've put up with this for too long already. Well, gotta run for now.....
