Just to clarify - are you talking about starting some 
long process such as printing a report, 
and then wanting to interrupt that process before it
is complete by hitting "cancel"?

AFAIK, since Eu doesn't do threads, it (and Winlib) 
are not going to be checking for button presses while 
doing something else. I think there's a peekEvents
call 
or doEvents or similar you could add to your print
routine to periodically check for queued events like
button clicks. After each line is printed, for
example.
I don't do Windows, however. Someone else will have 
to come up with the correct name.
