I'm having a continuous problem where Metro is getting corrupted to where it puts itself in SMPTE Display mode and won't switch back to Bar Display mode in OS 9. The only fix is to delete the preference file and reregister but it eventually gets corrupted again and I have to redo the process whick is a big PITA.
Are you saying the command-D does not switch back to bar display? Is it repeatable such that, for example, it starts happening whenever a certain file is opened?
