Illustrator, PDFs, and CMaps?

[AES]

I do a lot of editing of PDFs (and other files) in Illustrator, then
Save the final product to PDF format.

When I do this, I check the "Display PDF" option in the Save window;
the Saved file normally pops up in Adobe Reader; I review it and click
the red Close button, which Saves it from Reader; and I end up with
back in Illustrator with the same doc still open, so I can do further
editing and repeat the Save process if I want to.

Occasionally this process follows an unexpected path, where Adobe
Reader doesn't open (or maybe opens and pops closed immediately), and
I end up looking instead at a "CMaps" file or folder. Seems to happen
either if the PDF file has an unusually long file name, or has an
unusually large amount of complex vector stuff in it.

If I close this CMaps window, the PDF file still seems to be Saved OK
nonetheless, and I end up back in Illustrator as usual, so nothing
destructive seems to happen (sometimes the Saved file ends up with a
truncated file name followed by some random characters).

But I'd appreciate any education on what's happening here, and if
there's anything that should be done to avoid this?

Adobe Reader is nothing but a reader. Don't expect too much more than that.

Just save the doc as PDF on your HD. Open it with whatever.

Adobe Acrobat Pro gives you more possibilities.
