This question is probably so basic it's been covered a hundred times, but it's too basic to find a way to narrow down a search for the answer.
I have never been able to use submitted pdf files reliably as imported graphics in Quark (7.3). Either they won't import at all, and I have to save it down to an earlier version such as Acrobat 5 or 6. Or (even if saved to an early version) they import, but when I attempt to make a pdf of the page into which they've been imported, the nested pdf causes Quark to crash, at least 50-60% of the time I try. People keep telling me that eps is a dead format, so I suppose I'm doing the "wrong" thing, but the only way I can reliably import these files is to re-save the pdf files out of Acrobat as eps files. I just don't have time to try every submitted ad a half-dozen ways, and restarting Quark constantly, just to find out if it will work somehow. Eps is reliable. But of course that occasionally creates flattening issues such as drop shadows defaulting to 200 ppi etc. (which Adobe will provide no help for, since they consider it wrong procedure either to use eps or to use Quark).
I've tried printing to .ps and distilling, printing directly to pdf, exporting as pdf... same results. Quark will crash.
So the question is: has Quark ever come up with a solution for importing pdf files into Quark 7 documents, in such a way that, when I process my finished page as a pdf file for my printer, it won't cause Quark to crash?
