I have a treo 600 that used to be on a ATT network but now works on Cingular. For several months it has worked without any problems but now whenever I am on a call, it will pause and I have to keep touching the screen to unpause it. Its very annoying as I won't know when it will go into pause. The phone has never been dropped, placed near heat or water, and as far as I can tell, nothing should be causing any malfunction. I tried fiddling with the settings for the screen but nothing has worked. Google has failed me too so I am hoping someone here knows whats going on. Thanks.
