I tried it on an XP box at work, and the WinHTTP seemed to have problems - the dialog completed but there was not code posted to the listbox or the textbox. I also tried it on an French (France) NT4 sp6 machine and the script terminated early (it didn't crash, it just exited early ?!?!?!).

Anyway, like I said, I just tried it here (XP) and it worked like a charm. That's all I can tell you at this point.
