Hi,

Really, I don't remember when I used control-period successfully for the last time. Whenever I need to to stop an indefinitely running loop, I have to kill the entire IDE.

add this line as appropriate inside your loop(s):


wait 0 with messages


This will let the handler look outside itself for a brief instant, so that a mouseUp 
message can be generated by that "cancel" button.


You do know that cmd-period will abort any running hsndler, right?
