I'm having an issue with adjusting or customizing the rows/columns. All are appearing as overlapping blue boxes (see image below). If I choose a template that has several columns, they extend beyond the popup and I'm not able to scroll down to make any adjustments.

I've just noticed this happening since I've implemented the fix as described in this post: http://support.megadrupal.com/forum/module-support/mega-menu/98

Any help would be appreciated!
