Great news for Lion users:
Quark’s update to version 9.2.1 of QuarkXPress for Mac OS X is said to fix the “disappearing icons” problem that affects Mac users who upgraded to Mac OS X Lion 10.7.3.
It is recommended for all Mac users (there is no equivalent Windows update).
Quark reminds us that QuarkXPress 9 is the only version that is certified to run on Mac OS X Lion. You can download the updater from Quark’s website, or from within the QuarkUpdate preference pane.
