Can't type in IE when FullPage=False

This problem is sort of caused by two bugs:

Well, I found that in FireFox when FullPage=True, large amounts of content make the editor load very very slow, even to the point where FireFox tells the user that a script on the page is not responding and asks the user if they want to stop the script.

Anyways, I found that setting FullPage=False fixes the issue in FireFox. However, there was a side-effect:

When FullPage=False, you cannot type in the editor area in IE. Well you can if you know you have to click in the very very top left corner of the editor. Ofcourse my users are not programmers so they couldn't figure out where to click to get the flashing cursor.

Now I'm stuck doing a browser test to see if the user browser is IE then set FullPage=True, otherwise set FullPage=False. Sad thing is I want FullPage=True for all browsers.

So, my question is this:
A: How can I set FullPage=False and still be able to type in the editor area when using IE?
B: How can I set FullPage=True and not have FireFox break when there is a lot of content in the editor?

Any help would be most greatfully appreciated!

P.S. Although it has its own problems, FCKEditor is the best out there, hands down. You guys did it right when allowing so much customization options!

Thanks,
