Today, I found an interesting change in Visual Studio 2005 JScript debugging. In Visual Studio 2003, to dubug JScript we need to clear the Disable Script Debugging checkbox from Internet Explorer, Tools->Advance Options. But in Visual Studio 2005, we also have to add the key word "debugger" in JScript code.
