Bridge references acting oddly on my PC

I'm using Bridge CS5.1 (part of CS5.5), on a Windows 7 HP. Some weeks back I first began to notice that I had to reset my preferences every time I launched Bridge.

So, I tried tossing the Preferences file (using a google recommendation) but that didn't work.

Next, I had our IT department completely reinstall CS5.5, including Bridge, but that didn't see to work either. 

One other thing, perhaps unrelated, but my cache remained untouched. I thought that odd only because when we've reinstalled in the past, I had to completely reindex the library. That does not seem to be the issue with this latest reinstall.

Any thoughts?
