I just installed Quark 7 and have a list of issues. Tech support's remedy is to turn off Xtensions (which disables key features!), but nonetheless, did not work and I'm still experiencing a slew of problems. As of this morning, Quark has crashed 3 times, and I've lost my last set of edits. I've been using Quark for years, but this version is horrible, and seriously makes me want to switch to InDesign!
