I've tried all four methods of rebooting and one of them actually gave me a screen saying that the unit was booting (as opposed to jumping right to the acquiring banner).Michael P said:A rebooot fixes it for me. There is no way to get rid if it forever, it usualy happens to me when I get inpatient and hit a button on the remote a second time while the 921 is still "thinking" about the first time I hit the button.
