[Javascript] Heavy usage of ActiveXObject("Microsoft.XMLHTTP")hangs IE?

[John Warner]

First what does the code creating the instance of MSXMLobject look like?
What version(s) are you targetting? Have you looked at WinHTTP? Have you
looked at ServerXMLHTTP? Show us a bit of code here, maybe that is the
problem. I make extensive use of this object in several projects and
have never had a problem.
