I’m going crazy because all of a sudden I can’t access the C: drive from certain programs. If I want to download something in Opera, I have to download to Documents or something else that’s a library. In Gimp, I can’t access the file structure at all. I can’t figure out what’s wrong, and it’s driving me crazy. Windows 7 has a completely unintuitive suite of options for privileges. Windows 7 was your idea? I want to punch you.

P.S. I suspect that installing msysGit messed things up.

P.P.S. I turned off UAC and changed ownership of C: and everything in it to me. Reboot. Works now.
