Hey, that's why we're here. And there are lots of other people out there 
who will read these responses and find help, so you are doing a public 
service by asking. :)

I know, not specifically, but you will have to in order to get the 
results you're after.

It's the easiest and best solution, so you are on the right track. BTW, 
no operating system provides scrollable windows. What look like 
scrollable windows in other apps are exactly what you're implementing -- 
scrollable content in a fixed window.

Ok, in that case it's easy. When your script resizes the window, have it 
also resize the group. You need to do that because the locked group (it 
must be locked) will not change size automatically, it has to be told to 
fit the window. If the group's contents exceed the group's size, the 
scrollbars will activate automatically. If the group is large enough to 
accomodate all its contents, scrollbars will disable automatically.

The one liner I mentioned should be all you need in your own handler 
and/or a resizestack handler.
