Scrambled playback after Wizard remix

I have a repeatable problem where the video playback after one or more "Wizard remix" operations causes the video to only show bits of the picture scattered on a black screen.  Closing and reopening Creator fixes the problem.  I have only seen it occur after the "Remix" operation, not after the first use of the Wizard.  One or more remixes will cause this once the change is accepted and one tries to do a full screen "preview" of the show.

Edit:  Version 1.0.763
