I use my Droid for my main alarm clock. When I pick it up, if I am not holding it still and the screen rotates, the dismiss button moves to where the snooze button had been. When I am half asleep, I don't always notice this. I have accidentally dismissed my alarm instead of snoozing it multiple times. Anyone else have this issue or is it just me?
On the occasions I've used my Droid X as an alarm the phone was sitting in it's dock. Under that specific circumstance I have not encountered the same issue that you are experiencing.
