Didn't need to hear that last part. :o
Fiddler and the logs show 404 errors on the files. I can't figure out how to tell where specifically it's looking for the files. Here's one of the Fiddler entries:
Request started: "GET" http://localhost:12074/Reports/CrystalImageHandler.aspx?dynamicimage=cr_tmp_image_7c5abcc9-b5be-4241-9ea1-55ab8eaa070d.png
ProcMon shows the files being created successfully, and I see them in the temp folder.
What else should I look for?
