I have run into an issue with my keyboard. I use the Microsoft Remote Keyboard for Windows XP Media Center Edition. It uses a USB IR sensor. I am running Windows 7 Ultimate with all of the latest updates. Twice now the keyboard has locked up on me. Both times it has frozen while I was moving backward. I keep moving backwards and can't stop and no other key on the keyboard will work. Even the escape key doesn't work. The only way I can fix the issue is to unplug the USB sensor then plug it back in. This gives control back and I can then do everything afterwards. Just wanted to make the issue known.
Thanks,
