Hi Robin,

For your first problem: you can insert a 'flushEvents'
call at the end of your openCard handler ; this will
"eat" up all the events (or only those of a certain
type) that happened after the openCard started. You'll
probably want:

  on openCard
    disable button 8
    play "oct2002/sa1.aif"
    wait until the sound is done
    enable button 8
    get flushEvents(all)
  end openCard

But do look at the Transcript dictionary for all the
options.

As for your second issue: you'll need a repeat
structure ; though depending on what you want to
accomplish, it could be interesting to 'group' the
buttons and then work on the group.

Hope this helped,

Jan Schenkel.
