Ever since upgrading to OS 9 I have been experiences weird network delays and pitiful performance from Quark 4.1. I am happy to report that OS9.0.4 seems (at this point in time) to have solved those problems. Just wanted to let everyone else who was having similar experiences that the update seems to have solved those problems. I have had no other bugs show up yet. I downloaded the upgrade via ftp from the apple mirror (ftp://mirror.apple.com//mirrors/) rather than using the update control panel and had no problems whatsoever.
