Whilst looking more into the second beta release of IE7 yesterday, I came across the browser archive at evolt.org. This little gem appears to have most versions of most browsers from over the years, including a load of standalone versions of 32-bit Internet Explorer.

From what I can tell, there are most versions of most browsers in there (although there are some sizable gaps in the Navigator and Commnuicator arena) so now there should be no reason for a site not to work in a.n.other browser!
