I think my network guys are playing with IE policies again but I have an example from a book and it works fine no errors in firefox but when I try IE 7 or 8 it resets the connection. Has anyone else had an issue like this?
I'm am getting no errors from IE developer toolbar. I test with a simple window example from extjs and it shows up fine but I do this one example and it doesn't display.

I'm going to try it at home before I post any code or anything.
Just in case it is an IE setting.

And I do have the doctype set for IE to not complain.
