MovieDisplay crashes under Vista

Sorry to spam you all, as I am just repeating what I already posted 
at the PST Forum, but I want to get this on the record in case anyone 
needs to find it later.

I did PST's job for them and thoroughly tested the new MovieDisplay 
object on two computers under Windows XP and Windows Vista.  I tested 
every combination of StopAfter, EndMovieAction, and difference 
between durations of movie file and MovieDisplay object.  But the 
results can be stated very simply.

Under XP everything worked fine.  Under Vista, EP2 crashed whenever a 
movie file played to its end.  By "crash" I mean that Vista forcibly 
shut down the entire E-Prime application (E-Studio or E-Run).  Movies 
did play as long as StopAfter was set to Yes and the movie file had a 
longer duration than the MovieDisplay object, but in every other case 
EP2 crashed.

So we do have a workaround for those stuck playing movies with 
Vista.  Make your movie files a little longer than you need, set 
StopAfter to Yes, and make sure to set the Duration of the 
MovieDisplay object to something less than the duration of the movie 
file.  If you need the stimulus object to last only as long as the 
movie file, then put the appropriate duration for each file in the 
stimulus list and use that as an attribute to set the Duration of the 
MovieDisplay object for each movie presentation.  This leaves much to 
be desired, but may work well enough until PST fixes this.

Better yet just keep using Windows XP instead of Vista.  So far all 
my tests show that everything in EP2 works fine under XP.
