SharePoint Browser Support and SharePoint Browser Compatibility
Also going to post this one in response to a question I just had related to Browser Compatibility.
Ever wonder what SharePoint supports in terms of each level browser? Microsoft released (way way back) two great articles that fully explain how SharePoint supports each browser and the level in which they support it.
SharePoint 2007 – http://technet.microsoft.com/en-us/library/cc263526.aspx
If you ever wonder or need to explain why users should use the latest version of IE over those other browsers when viewing SharePoint just refer to these articles.
Hope this helps someone,
