Some people prefer one over the other, some read both. For the best 
possible coverage, I'd say post both places.

While there are a lot of professional developers here on the list, any 
kind of question is welcome. We don't necessarily have to be the 
"advanced" list. Anything is fair game. Fire away.

Someone already suggested looking at the formattedheight and 
formattedwidth of the field, which would give the info you want. That 
would work fine. Another thing I sometimes do is just set the scrollbars 
permanently. If the field fits, they'll be blank and pretty much 
unnoticeable. If the field overflows, they automatically enable. The 
engine knows.

Another trick is to put the entire contents of the card into a group 
which is the same size as the card. Turn on the group's scrollbars. As 
long as you have a resizestack handler that sets the size of the group 
to the size of the card, the scrollbars will take care of themselves. 
This only works though if you are happy allowing the entire card's 
contents to scroll rather than resizing all the objects on the card.

Can you explain more about what doesn't work?
