I work at the Real Estate Book creating the ad pages. We use Quark xPress 4.01 because the print house is fully automated for that version. They haven't been able to test above. I really liked the demo of Quark 6, but noticed that it can only retroactively save to version 5. Is there a plugin or something that will allow a fully compatable 4 save? Please and thank you for any and all help.
