I use Quark 6.52 with my new MacBook which has the 2GHz Intel Core 2 Duo processor. In a few functions in Quark, such as "Delete page" an incorrect version of the delete window comes up and then I end up having to restart my Quark. There are other lesser examples of the problem but I am wondering if this version will run well on this computer or whether I may be faced with upgrading to 7. I am in the middle of a book project now and don't want to do that if I can avoid it.Help!
