Example of scrolling group?

[Douglas]

Thanks Bernd,
That certainly helped me out, and also shows why I was getting grey 
rectangles instead of scroll bars.
I copied your example and made a test stack like yours.

Jeff M. -
Here's some stuff I figured out:-
If the window size is larger than the group and the hScrollbar or 
vScrollbar is true then the scroll bars turn into these grey rectangles.
You can set the maximum width and height of the card to the original 
group size - that will leave the full scroll bars at max size.
You can set the hScrollbar / vScrollbar  to false if the window is over 
the group size and the scrollbars will vanish when the window is changed.
Or just don't allow the user to change the window size at all!

The scroll bars are included in the group, so the group size is original 
group size PLUS the scroll bar width (16 by default).
(Otherwise the scroll bars obscure the group fields etc at the edges.)

When you are changing width or height of card within a card script, you 
need to keep track of the scrollbars with a resizeStack routine as below.
Bernd has introduced  a little interest below by putting in the 30 pixel 
offset from the top of the card.
I found that a little confusing when messing about in the IDE and 
changing window sizes etc.

I should be able to get on with it now, thanks again, Bernd
