load function not working in IE 9

load function not working in IE 9

I use the load js function to load the navigation menu on most html websites I build. I use it on my website http://syntrixsolution.com. However with the release of IE 9 just recently, according to adobe browser labs the load function is not working. Is anyone else experiencing this problem? Don't tell me IE 9 is not going to allow this to work. It works fine in IE 6, 7 and 8. Any help appreciated. I use a mac so can't test properly as my VMware is running vista which doesn't allow IE9 to be installed.
