When I open a report through a web page, Internet Explorer displays an alert box saying: "This page is accessing information that is not under its control. This poses a security risk. Do you want to continue?"
Why is this? I have another project with identical code, config and references and it works fine. Why not the same behaviour?
The only difference between the reports is that the reports causing the alert were opened and saved in VS2010, causing them to be "upgraded".
