Users & Groups frozen? Help?

I'm deleting an account I used this past semester as a study zone on OS X Lion and it seems to be taking forever (hour+). I'm not sure if it's frozen or not, and I'm sort of nervous about force quitting it/logging out. I've never had to wait this long in the past to delete an account. I'm on 10.7.4.

Is there anything I can do?

Edit: Nevermind, it just took two hours.
