Just for the sake of accuracy,  in HC & SuperCard , the mouse function does 
NOT necessarily reutun "down"  if the user clicked anytime between when the 
handler started and when the function is called. Both SuperCard and 
HyperCard return the actual state of the mouse, up or down, whenever the 
mouse function is called within a handler, at least under Mac OS 9. Perhaps 
it works differently in OS X.
