Wouldn't it be good if it was just a browser refresh to cure it?
Unfortunately all 3 browsers I use to test sites I build all produce the same ugly text. I'll try Chris's suggestion but I'm not planning on re-editing 160 listings just because an update of CC caused all the fonts to go large.
Thanks for the suggestion Chris but its the heading of the listing that is seen on the front page and That doesn't have any way to change it that I can find. I've been through each menu option and can't find anything vaguely related to font size. Your suggestion is a one by one edit of what I've already done when listing the sale goods. Pity. Cube Cart looks nice in the demo sites but in all seriousness... If a developer puts out an update and it does this when you install it, this is not a product I want to open the doors with.
