I hope some of you paid close attention to the very good advice Kjell Krona
gave in message <1180@ttds.UUCP).  He made the very important point that if you
have a script that needs to be repeated in a lot of buttons, you don't need to
duplicate it for every button.  In fact, the buttons DON'T EVEN HAVE TO HAVE
SCRIPTS.

To reiterate Kjell's message, move the mouseUp handler to the card, background,
or even stack script.  If you need to differentiate between buttons, use the
button name to identify the different classes of buttons, then have your
mouseUp handler check the "name of the target" and act accordingly.  You can
even put "parameters" in the button names.

This can make your stacks MUCH smaller and much easier to modify.  The cardinal
rule of good, structured HyperTalk programming is "If it's duplicated, move it
up the heirarchy!"
