I have a web app (VFP + Web Connect) running for 3 years. Suddenly, this week a user complaints that "the app broke". It was downloading reports in PDF and XLS format to the client fine. Now it wants to download HTML only. What changed? They upgraded their browser from IE 5.5 to IE 5.5 with a much later build (from 4134 to 45xx or similar).

The same happens with attempting to download .DOC, .XLS, and sometimes .TXT

Anybody has an idea what has changed? Any settings I can tweak?
