At a recent wedding, my second GL2 suddenly would not go into Record mode when returning from Lock to Standby. The LCD and EVF were black. I tried VCR mode and it looked normal. I then tried rebooting (so to speak) by shutting the power off. No change. I tried removing the battery and restarting but again, no change. I put the camera away and went with the first cam.

About an hour later at the reception, I tried the cam again and it behaved normally. Any ideas what happened?
