I was having the same problem with groups -- if I made any of the items 
in the group extend below the group, the group bottom would shift a 
bit, and it would eventually disappear below the bottom of the window.

What I've done is create a preOpenStack handler and in it I size and 
locate the group before the stack opens.  Then I override the 
resizeStack handler, and do all the group resizing manually.  Do the 
size calculations yourself, it takes no time at all, and I've had no 
problems with the group being the wrong size since.  Oh, and be sure to 
turn off all geometry (check it twice that it's off), and turn on "Lock 
Size and Position".

By the way, is there an FAQ somewhere?  I'd like to add a couple of 
things I've found in the course of creating this photo album product 
I'm doing.  For example how drag and drop really works (i.e. you don't 
always get a dragEnd message), as well as how cool groups are once you 
decide to handle the resizing yourself, how to scroll a group on the 
fly, etc..
