Multiple Programs Not Responding after right-click

Hi all,

I believe I've had this issue before, but I don't remember how (or if) I solved it. Whenever I right-click in all Microsoft Office applications (Word, Excel, PowerPoint) as well as uTorrent, I just noticed, I get the rainbow wheel and have to force quit the program. It's possible that it happens in other programs and I haven't noticed, but it's really annoying.

Anyone know how to solve this?
