Hi Tim,

The way I read the docs, you should set the local
property allowInterrupts to false before going into
the repeat loop. So the script should look something
like :
--
on mouseUp
  set the allowInterrupts to false
  repeat
    if the interrupt
    then cleanThisUp
    else add 1 to msg
  end repeat
end mouseUp

on cleanThisUp
  put "I'm interrupted" into msg
end cleanThisUp
--

A quick test revealed this to work on my Windows
machine. So I hope this helped,
