Not to spark a Quark vs Indesign debate, but I have an odd problem with Quark. I installed Quark 6.0 on my G5 running OS X. No problems. Then I installed 6.1, again no problems. I installed a brand new copy of Quark 6.0 on a G4 running OS X. No problems. I ran the 6.1 updater and Quark won't work. It tries to start up, but either it runs on forever, or it quits. Anyone know what the deal is? Is there a fix for this, other than switching to Indesign?
