Browser specific

I see that you are using Firefox/3.0.7. on Windows XP.

Try Internet Explorer.
Or
Try downloading and installing Google Chrome or Apple Safari or Opera or Netscape.

It might just work fine in some other browser.

Try also FCK editor in more then one single browser.

Sooner or later you will find platform/browser/editor combination that works.

I am sure developers of TinyMCE are working on fixing all brwser specific bugs.

Some new version of TinyMCE might just work fine on Firefox/3.0.7. on Windows XP
