I'm having the same issue.
However, the example link looks fine on both browsers.
So I'm wondering: is there a minimum Height on the cute editor?
I need it to be no more than 100 pixels high, and it looks roughly twice that. I can't seem to get it smaller.
(and I have the toolbar turned off, and am showing the footer bar so if a user wants it larger after the page is loaded, they can click the +/-)
