That's because when you create object with 'new XMLHttpRequest()' as builtin
jscript extension it's always acts as asynchronous with installed event
handler.

If you do ActiveXObject() it's created as a normal COM object and operated
through IDispatch, jscript extension for this class acts as a wrapper over
msxml implementation and doesn't even use IDispatch as you may see in logs.

I'll open a jscript bug for that.

Yeah, that could be caused by urlmon problems or a real bug in httprequest in
msxml itself.
