Brobotnik, we should see if we have any similarities! Maybe we can narrow it down between us.

Do you by any chance have VMWare, GoToMyPC, or Teamviewer installed? I have all 3, for work purposes, and I could see them possibly interacting with it. They're a huge hassle to disable, however, so I haven't tried to troubleshoot it that way yet.

Also, I'm running Windows 7 64 bit.
