Possible Goofy Fix Found for Missing PlayStopped

[Scott Rossi]

After spending the better part of today messing around with players, sound
files and wet towels to clear the bloody remains from my forehead, I may
uncovered a goofy fix for the missing playStopped message Jacqueline and I
batted around in December.  The RunRev folks may have already implemented a
fix for this, but in case they haven't, here's a recap:

OK, so while playing around with this stuff, I tried to find some way to
force update the player or the card, and discovered by accident that
resizing the stack causes the loop to continue.  So I created a repeating
handler that continuously sets the rect of the stack to itself (hey, I said
it was goofy, I didn't say it was pretty).  The above script was modified as
follows:

 on playLoop
   global gPlay
   if the shiftkey is down then -- stop loop
     put false into gPlay
     stop player 1
   else
     put true into gPlay
     start player 1
     goofyFix
   end if
 end playLoop

 on playStopped
   global gPlay
   if gPlay then playLoop
 end playStopped

 on goofyFix
   global gPlay
   if not gPlay then exit goofyFix
   set rect of this stack to rect of this stack
   send "goofyFix" to me in 100 milliseconds
 end goofyFix

The strange thing is, even though the script seems to work, the playStopped
handler won't return the name of the stopping player, which almost leads me
to believe whatever mechanism is handling the player messages is leaving out
that information somewhere.

Anyway, hope this is useful for folks in the interim.
