I tried to reuse a script that uses the setHomePage method, that worked fine few months ago on both IE 6 and IE 7. Now it still works in IE6 but comes up with an runtime error "Permission denied" in IE 7, and the script debugger point at 'document.body.setHomePage('http://SamePage.astheSciptIsRunningOn.com');'. I tried the example on the this page also, and other samples that have been working so far, but IE 7 always comes with this error. I found a few post where other people have run into this problem recently, but no explanation or solution. Have there been some changes in the IE 7 security that prevents this method to run? I am testing on Vista Ultimate SP 1, with IE 7.0.6001.18000.

Sorry, this was a misunderstanding. I found out that there had been a recently implemented group policy on our network, that prevented users from changin the home page.
