Wow - punching holes in stacks!

[David Bovill]

Well creating a new stack adding a button with this script and clicking on
it works here:

on mouseUp
>     set the backgroundcolor of me to blue
>     set the ink of me to blend
>     set the blendlevel of this stack to 5
>     set the rect of this stack to the screenrect
