Substacks in revlets

[Richmond Mathewson]

I just made a stack "MAINN" with a substack "SUBB"
and popped a button right in the middle of "MAINN"
with the script:

on mouseUp
   palette "SUBB"
end mouseUp

built as a revlet.


Didn't work . . .

Now is this because 'palette' is causing problems,
or is it just that revelts don't like substacks?
