Whenever I try to right-click in explorer instead of bringing up the menu Windows explorer crashes and I get dumped back to the desktop. Programs still run but any directories that were open close. I get the same thing when I select a file or folder and press the delete key. Just wondering if anybody knows what the deal is here.

I can right-click in the directory window, just not with a file selected.

Which OS are you running? Could this be your problem (here if it's Windows 7)?

I forgot to mention it's Vista.

Well, there's your problem.
