[AccessD] Need rectangle with rounded corners

[Rocky Smolin]

Dear List:
 
I have a requirement from a client for a purchase order where they want the
Vendor, Bill To, and Ship To info in a rectangle with rounded corners.
 
Been trying to make one that will stretch with no luck.  Not an image off
the web.
 
But I'll bet there's an easy way to this this that I'm not aware of.
 
What is the easiest way to create a stretchable or zoomable box with rounded
corners.
 
MTIA,
 
Rocky
