Adam:
Sorry for the theatrics, but I am pretty annoyed. I would have delt this with more gracefully if I didn't have so many people trying to tell me to rtfm after I had spent several days figuring this out and getting questions from potential customers asking why my website was so screwed up.
All I'm looking for is a simple answer so I can decide whether to wait for a fix from CC or rebuild my site with another program.
Not a fix but a temp. workaround that I use: after I created the HTML pages (via the Save option), and before uploading, I run a script that does a global search-and-replace for "font-size: xxPX" and change them to "font-size:XXEM" (or PT depending on your choice) so that font-scaling within a browser works.
