tiny-mce script error freezes the page

This error message keeps popping up when I try to edit a page. The entire screen freezes. How can I fix this? Here is the error message below.

A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
