Dashboard module problem

Hello;

I some how in my post editing noticed the line going through the edit window(Where you type the text) and the line said “thank you for composing with WordPress version 3.3.1

I tried to remove it but to no avail and now the edit window is way down below (under the fold) at the very bottom of the screen and the line is still about half way up the page. I cannot move any of the modules around including moving the edit window back to the top. At the top it still says “enter title” yet the title bar is at the bottom.

Can someone tell me how to get the dashboard back to normal?

Thanks!
