It's different in the sense that a click will generate both mouseDown  
and mouseUp events. So if your mouseUp depended on anything that be  
set by mouseDown, Klaus's idea is probably better.

Also, manual clicking will ensure that the stack with the button is  
the defaultstack and possibly the topstack. Depending on what action  
your mouseUp handler takes, could that be a factor?
