Emergency - (sort of) "a stack name with the same name..."

[Chipp Walters]

Try clicking on the 'messages button' to turn them off. Also, try working
the task manager, sometimes it will 'interrupt' Rev long enough for a
command-period exit. If you sometimes hit the enter or return key, it will
default the hidden dialog, and there's a moment when you might be able to
command-periode as well.

If you can see the dialog, try ctrl-clicking on it and see if a menu won't
popup where you can close it.

Hope you get it fixed...Always Backup.
