Internet Explorer 9 has been released and there are already compatibility issues with some departmental/academic applications, including OnBase and TigerTracks. Blackboard also has some minor issues.
Until the university upgrades to OnBase 11.0, OnBase will not be supported on IE9.
TigerTracks/Footprints appears to work with IE 9 when "Compatibility View" is enabled (see here for a Solution Guide).
Internet Explorer 9 has not yet been certified for PeopleSoft. If you are already using IE 9, turn on the "Compatibility View" option when using CUBS.
Blackboard is not officially supported on Internet Explorer 9.
There is a GPO in Active Directory to prevent domain-joined computers from upgrading to IE9.
