Mine was doing this too. (I am running a stock WM6.1 VzW rom.) I had added some dialer cabs. I took each one off, soft resetting after each removal. Then I added them back, one at a time, soft resetting after each add. Now I have all my dialer cabs back and no "disappearing dialer screen."

BTW, I've been told that you should screw with the dialer on a stock rom. But you know, I don't listen very well!
