Unresponsive User Accounts Controll Pannel

Ben

I'm simply trying to turn off the User Account Control under User Accounts. I
just now noticed that the link to turn it off as well as every other
administrative-required (denoted by the little shield) are utterly
unresponsive when I click on them. The problem is solely in under the User
Accounts portion of the control pannal. I was wondering if this was a known
bug?

*note* I am the administrator, and the only account on the system for that
matter. I am also not connected to any network other than my own router.

If anyone has any suggestions of patches or ideas please let me know! I
really don't feel like trying to re-install Vista for the 3rd time.

Thanks,
Ben
