The signals are added to a queue but don't get a chance to fire, 
presumably because the arrowkey message is happening repeatedly. Queued 
messages need some idle time before they'll execute.

This might work better if you add "without waiting" to the move command, 
allowing the handler to continue immediately, and then call the 
animation handler directly without using "send".

Try rawKeyUp, but you may not need that if you change the move command.
