Thanks for the advice, but update did not help. Am experimenting w/links, but most of the links that look like they could be a problem, have been packaged before in many other projects. It's a mystery so far.
Yes, those are files, like I mentioned, that have been copied numerous times already, without incident, no problem. Thanks anyway. Could they just start to be an issue, after having been used successfully so many times?
Just wanted to say thanks. This thread solved my problem as well. I had a link with a slash in the filename and I couldn't package the document. I had packaged that link previously and it worked, but whatever. Renamed the file and the document packaged fine. Thanks Bob.
