In the admin backend when using IE8 the floating form element picker does not display correctly. The picker is partly off screen and you can only see the first 3 elements in each tab and none of the others.
In IE8 the Select Element does not work as you cannot edit new drop down items.
Finally the option to add a description to form elements does not work in IE8. When you click the text the textarea control is not shown.
I am using the latest release of the software.
