Really obvious question, but have you turned it off, and turned it back on yet? My motorola phone has the same UI as the Razr and occasionally it needs a reboot just like a PC.
Just hold down the cancel call/hangup button for 5 secs, then again when it's off if ya didn't know - again prolly obvious stuff.
If that doesn't work, pull the battery out for about 5 mins, then put it back in and turn it on.
