Hi Bruce:
Mainly, you'll have to look at the user interfaces.  All the background 
processing will run unchanged.
You'll get into things like Fontmetrics, the various fonts themselves, and 
the Report Forms.  If your reports were all "hand-coded" this won't present a 
problem until you decide to convert.  (And... when you do, I strongly 
recommend Crystal Reports 5.0.)
So, screens and reports.  The menus work the same.  The popups are the same.  
Just be prepared (and prepare the client) for slightly different looking 
screens and a burst of SPEED!  :)
I wish you well, Bruce.
David in Dallas.
