Jim,

A lot normal properties are hidden in the style.vcx that's how it works. Greg gives a fine explication how this class is built and works.
It seems this topic goes about 3 different things, but afterall all related to each other (1. the original question, 2. your nice solution to resize a from based on a font size and 3. implentation of 2 into style.vc from Greg)

Best regards,

Koen
