>>When we install VFP7 we have this nice JIT debugger installed as well. JIT fires when there is a script error on an HTML page. After I installed .NET this is not happening anymore. All I have is a message on a browser status bar: "Error on page". Is there a way to get JIT functionality back?

You are right. Hell, why has it been disabled?
