I dont know if anyone else have had this issue but, i just got my atrix last week and everytime I Connect the phone to the pc (Via included USB cable), the touchscreen freezes (cannot select anything) also none of the keys respond. i have to take the battery out and reset it. Only happens when i connect the phone to PC. Tried it on both my laptop and desktop running windows 7 (have the latest drivers installed) and still freezes. I have latest software 1.5.7 and the phone is rooted. Any ideas?
