[Plugin: Adminimize] New post: white on white!!

Hi,
I’ve just installed Adminimize and I don’t set any options!
So, if I log in like contributor in my site and I add new article/post: I’m write white on white! Why this?! I can’t see anything! If I selected text area with my mouse I can see that I had write something, but text color is white on white background 🙁
Sorry for my english 🙂
