Has this ever happened to anyone elses touch pro? I have set the device to lock via th long key press. When I try to execute it, all that happens is my phone goes to the home screen - but it does not lock. Is there another setting somewhere I have to do too?

That happens to me on occasion. Releasing and holding it again usually gets it to lock. I suppose you have tried it multiple times.

Happened to me awhile ago. I tried to set the long press end key to a different function, but it didn't help. It would beep after 5 seconds of pressing, but not perform the function.

I had other issues with the phone at the same time. The onscreen keyboard would default to numbers/symbols instead of letters and I couldn't get it to switch back.

There were other problems as well. I have a post about it on these boards. I had to hard reset the phone, since not being able to lock the phone would make it randomly dial out, since I keep my phone in my pocket.
