Since we can't disable the digitizer on the screen I'd try another keyboard and watch the user for any action by them that is near the screen. You don't want to know that one time we had to video tape the owner since they didn't believe it was their fault. Incredible.

I have a new 32GB ASUS Android Tablet with add-on OEM keyboard and love it for speed, display, just about everything.
BUT when typing, no matter what software I'm using, the cursor JUMPS SPONTANEOUSLY in the text--a huge problem for typing of any sort, but especially for note-taking at a meeting or class. I wonder whether other Android users have noticed this, and may have a fix?
