I'm having a problem with my Control Panel Add or Remove Programs section. I'm used to it sitting for a minute or two while it says "Please wait while the list is populated" or whatever, but I can now leave it for an hour or two with nothing happening beyond that message. More so, when I close the window, I can't open it again until I kill the rundll32.exe process in Task Manager. I'm now forced to use a 3rd party app (MyUninstaller) to get rid of stuff.

I've run AdAware, Spybot S&D, and a full F-Prot virus-scan... nothing. Anyone else ever experienced this or know of a fix that I'm too oblivious to see?
