Changing the screenRect within a stack

Hi Francis,

Accustomed as I am to running a variety of applications pretty much at  
the same time and interchangeably, I feel you should stick with your  
first approach. Let the user determine what to do. Just make some  
suggestions, advising the user in advance of the various repercussions  
that might occur with different screen resolutions; OR, optionally, if  
the user's screen size is going to be too small, design your  
application accordingly - even providing horizontal and vertical  
scroll bars; or, as PDFs do, perhaps the ability to zoom or move  
around using the hand tool.

You may be worrying too much, since many of us DO have a lot of real  
estate these days. Just announce the preferred screen size for best  
performance in advance as part of the system requirements and let the  
user worry about it. Surprise is the worst thing.

Just some of my thoughts on a late Sunday afternoon.
