You may notice some of the following issues:
- Drop down menus not working
- Issues with Gradebook rows/coumns
- Unable to reorder items
Not all users are experiencing all the problems, some experience none of the above. We would recommend not upgrading to IE9 in the short term, if you already have upgraded or you are accessing Wolsey from a computer that you do not have control of, you will need to put IE in to "compatibility mode".
You can find more information about "Compatibility Mode" here.
