Great, but messes up WordPress CSS

This is a great plugin, but I had to inactivate it on my wordpress site. When it was activated, much of the css that styled the dashboard (especially under “Appearances” > “Menu”) was messed up. For example, all the menu items were left aligned on the page instead of submenus being nested under menus like they are supposed to be.

If this was fixed, I would love to use it again!
