Has anyone else had this problem [Moto Droid] ? Here's how what happens. When I'm using messaging, and I'll let the screen off. Everytime I turn the screen on via top button, after unlocking the screen with my finger, the phone freezes untill this comes up: " Sorry! Activity Messaging (in application Messaging) is not responding. " Then I'm given the options "Force Quit" & "Wait". This happens everytime I let the screen turn off or lock the screen while in the messaging application. I'm considering going to Verizon and getting a replacement tomorrow since there is no cost for a replacement device. Any Comments?
