This is really getting irritating for me. Rt is asleep, I go to wake it up, touch the password field, cursor flashes in the field...but I can't type anything! On screen keyboard won't engage and if I try my touch cover, nothing happens with that either. The only ay to remedy this, as far as I know, is to restart. I'd say this happens 1 out of at least every 3 times i wakeup my rt. This opens with 8 and 8.1. any ideas on how to fix this incredibly annoying bug?
