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

[Hakan M.]

Oups, accidently hit ctrl+enter there.

I'd like to add that we've done quite some testing to pinpoint the 
problem down to the ActiveX-object, we're fairly sure this is where IE 
freezes. What I'm looking for is both a confirmation/explanation on this 
behaviour, but I'd also like to know if anyone know of an alternative to 
using the XMLHTTP-object. All we really want to do is HTTP loading of 
(text)files.

What would really make me happy is a reply from someone saying "hey 
bozo, use the Microsoft.HTTPLite instead, it never crashes and won't 
load major overheads (or whatever makes XMLHTTP crash) for every request!"

And then I'd like a car that can fly and run on water.

Thanks in advance,
Hakan
