Windows 7 Desktop does not save theme/ KVM

Has anyone else had this happen. You set a particular theme and it disappears on reboot. Then...downloaded themes from MS disappear.
Also, I'm running this test pc next to 2 pcs running XP pro. All of these are hooked up to a KVM. Every other time I boot on the win 7 pc, theres no response from the Logitech wireless keyboard and mouse.

Anybody else?

I wish I was drinking, then there would be an excuse!
