Thank you to everyone for their help. I finally figured it out. It was a
caching problem. In our Application.CFM -- which hadn't been changed in over 3
years, there was a line:
<CFHEADER name="cache-control" value="no-cache, no-store, must-revalidate,
post-check=0, pre-check=0">
I took out the "no-cache" and "no-store" pieces so that it read:
<CFHEADER name="cache-control" value="must-revalidate, post-check=0,
pre-check=0">
And it started working. I got the clue from reading other threads with similar
problems trying to open Word and Excel files. So hopefully this post will help
someone else out. :-) Dawn
