I installed Quark 7 but now find that some of my printing vendors are not supporting Quark 7. Is is "safe" to open my Quark 7 files in 6.5 without any formatting changes. All my quark 6.5 files are by default opening into Quark 7 when double clicked. I would prefer they open into Quark 6.5 as if Quark 7 did not exist on my computer (all the icons have changed as well.) Is there a way to change this globally without going into each individual file. I tried used GET INFO and "use this application to open all documents like this" but OPEN WITH automatically goes back to QuarkXpress Passport. I have File Buddy but the resource and creator types are the same for both 6.5 and 7.
