We have one machine (Mirrored door G4) running panther and Quark 6.5 that with Quark only is so slow it it unusable. I have cleaned up the fonts on the machine and reinstalled Quark with no improvement. It takes many minutes to up any document, the interface runs very sloooooow and opening the print dialog takes a long lunch break. Anyone else run into this? We are a medium sized print shop running this version of Quark on a variety of G4's and 5's without the same problem.
