I might be mixed up on what you are trying to do.

To do "something else" only once each time the mouse goes down you can 
try this.  Set a script local flag in a mouseDown handler.  Check it 
and clear it in checkMouse.  (I'm not sure if this is what you are 
asking for.)

If the problem is multiple checkMouse cycles, you should see it in the 
"Pending Messages" view of the message box.  This is a common problem.  
One approach is to keep the message id in a script local and have 
checkMouse and its starting and stopping commands maintain that.

You might want to look at my "Message Mechanics" primer (very slightly 
dated) that is here:
