Widget Issue in Version 3.5

The widget section is completely full of bugs. Whenever trying to edit or move any widget, the page glitches (in every browser) and the widget clicked on appears and sticks on the page as shown below:

The widgets cannot be edited, changed, reordered, or anything. Worked until update to version 3.5 after going through multiple versions of WP just fine.

Everything else seems to work okay with the new version, but the widget section has been completely broken, and from the looks of the www.remarpro.com forum posts, this seems to be a common problem.
