After I upgraded to WP 3.3, I have had 2 issues with ckeditor. The first is with a Genesis theme. The widgets page would come up blank until I deactivated ckeditor. The second issue was with another theme. In IE, in the dashboard, when I hovered over any of the tabs, the dropdowns would not dropdown. And also on many of the pages, the ckeditor editing tools (icons) did not show up. When I deactivated ckeditor, everything worked again. With Mozilla, the second issue did not happen. Is anyone else having issues with ckeditor after upgrading to wp 3.3?
