Version 1.4.1 & 1.4.2 crash customizerd IE 7 when "native XMLHTTP support" is disabled

After doing a lot of testing and research to determine the cause of an IE7 crash, I have figured out that when a version of IE7 has been distributed using the Internet Explorer Administration toolkit the "Enable XMLHTTP Requests" option is disabled by default. This disabling will cause 1.4.1 and 1.4.2 (not tested with 1.4) release of Jquery to crash IE. At this point the task must be killed in windows to recover.

You can manually go to a ie7 instance and disable this feature under advanced option -> security, which will allow you to reproduce the problem. Another way to determine if the browser has been custoomized is to look at the IE version infor under help. The customized version is indicated with a "CO" at the end of the version. The specific versions this was tested under is 7.0.5370.13CO and .11

IE7 with native XMLHTTP support disabled works for me with current versions of jQuery without crashing.
