Keyboard Freakout

Hello all,

I'm running the latest version of Desktop and every once in a while I get keyboard freakouts under XP. Basically, I'll be working and they keyboard stops working normally and starts deleting characters in the doc I'm working on or acting like CTRL+ keys and opening lots of Explorer windows etc. I have no idea what sets it off or how to fix it once it happens. Any idea what might be doing this and what fix might be?
