Scirpt Error In Wordpress

I am consistently getting this error in wordpress when I try to write
a new post. It freezes up my screen and I do not know how to fix it,
please help:
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.
