Thread: Internet Explorer freezes up when searching

if it's a development / compatibility case then I'd suggest using IETester, I've been using it a lot and it's very handy

IETester is a free WebBrowser that allows you to have the rendering and javascript engines of IE8, IE7 IE 6 and IE5.5 on Windows 7, Vista and XP, as well as the installed IE in the same process.
