Hi William,

Initial thought: use the 'selectionChanged' mesage -
whenever you type something or remove text using
backspace or the delete key, this should be sent.
So try this:
##
on selectionChanged
  set the enabled of group "test" to (the text of me
is empty)
end selectionChanged
##

Hope this helped,

Jan Schenkel.
