Yeah...I don't expect it to display inline on all browser/os/viewer combinations, but it should at least ask to download, and it seems to be.

I also have had some issues with sending the right headers when serving up files with PHP, but my current configuration seems to work well in all the various combinations that I've tried. That said, I'm sure there are some combinations somewhere that don't work, and I'm going to work with my critic to get it to work, cause I'm just nice like that .
