Hi Michael,

It has to do with the moment the state of the mouse is
checked. Maybe you could rescript your button so that
it uses the mouseRelease event ?
Example:

on mouseDown
  send "updateMe" to me in 50 milliseconds
  -- or however quick you like
end mouseDown

on mouseRelease
  if "updateMe" is in the pendingMessages then
    cancel "updateMe"
  end if
end mouseRelease

on updateMe
  -- do your stuff here
  -- ...
  -- now call yourself however quick you like
  if "updateMe" is not in the pendingMessages then
    send "updateMe" to me in 50 milliseconds
  end if
end updateThings

Hope this helped,

Jan Schenkel.
