Yes, with the default dynamic behavior of groups this is what most folks 
will experience.  But some time ago I needed more canvas-like behaviors, 
and Scott Raney accommodated me by adding the boundingRect property for 
groups.

Similar to SuperCard's backSize property, the boundingRect lets you 
define a rect for the scrollable area of a group regardless of its contents.
