I normally don't use PostScript, but I think the problem is that PS is really designed for printing and not viewing. I could be wrong, but I think you will lose the hyperlinks as you pass through PS. The hyperlinks are the only reason I'm even considering PDF (and maybe HTML) in the first place. If I don't have hyperlinks I'll just leave it as plain ASCII text.

I also find it interesting that, at least according to Adobe, all PDF readers are SUPPOSED to be able to read all versions of PDF documents. If an older reader is trying to read a newer document it should just be able to ignore what it doesn't understand, but that doesn't seem to happen (at least not from what I've seen).

Bocke:

Obviously your experiments with different VMs turned out differently than mine so the problem is not just with the VM itself. It could be a VM version, a configuration setting, the DOS version, the memory manager, or who-knows-what. I get errors and and/or the reader instantly exiting without even attempting to display anything.
