Hello, I have a web application coded in C#/ASP.NET. The application basically exports a PDF file when the user click on Save. It then reloads a DIV, putting the EMBED (with the src pointing to the newly generated pdf file) in it. Sometimes the embed area just gets black and I get this window from Acrobat Reader: http://img180.imageshack.us/img180/3359/acreader.jpg. What does it mean? Has anyone ever see this?
