As students may have computers which have been updated to Internet Explorer 9 (IE9) or have bought a Windows 7 PC which will have it installed as a matter of course I thought it would be timely to pass on known issues with Heritage.
It appears that Search will work when users are not logged in but once they have logged on the search feature no longer works.
IS Oxford have released a patch to update the JavaScript in Heritage Online but other Heritage users are still reporting problems. Please let me know if you have any students reporting issues related to using Heritage on IE9 and I'll arrange for the patch to be applied.
