It sounds like a conflict between the keyboard drivers and MultiBox and unfortunately without such a keyboard it would be very hard to figure out what is going wrong.

As for the not being able to type, try pressing cntrl, alt and shift once each to see if it solves the problem. Sometimes those keys can get stuck in the pressed state and will cause some wierd problems.

If anyone knows exactly how (on a programming level) the G15 works it could help solve the problem with it.Does anyone else with a G15 have trouble?
