Mouseover actions, reply and assign menu not working since 8.2 upgrade

Hi, since upgrading to 8.2 the mouseover actions on the Reply, Actions and Assign menu not working correctly, the text appears to the top of the screen and cannot be selected.
This appears to be an issue on all browsers I've tried, have cleared history and temp files, also tried compatibility mode.
