Ah yes, the age old UFO of programming, debugging in ASP.

It is possible, but because ASP is so easy, and the fact that it's scripted, most ASP 3.0 developers don't even bother with debugging features of Interdev. Instead, they just use it with the attitude, "Hey, something came with VB6, so might as well use it for the syntax highlighting."

In fact, you can just code in notepad.

Anyways, it is possible, but on limited OSs. I know it wasn't possible in Win 98, but I had seen it on Windows 2000.
