Hi Jason,

I modified your program slightly.  The main thing I noticed was to take 
out the lock screen.  This made things pretty snappy.  The faster the 
computer, the faster the transition.  I put this code at the card 
level.

on keydown thekey
   put thekey
   if thekey = "1" then
     stop player "B"
     put the currentTime of player "B" into Atime
     hide player "B"
     set the currentTime of player "A" to Atime
     show player "A"
     start player "A"
   end if

   if thekey = "2" then
     stop player "A"
     put the currentTime of player "A" into Atime
     hide player "A"
     set the currentTime of player "B" to Atime
     show player "B"
     start player "B"
   end if
   pass keyDown
end keydown
