In Firefox 3.6/Win the cursor disappears after maximizing ckeditor. It does not reappear even after switching back (pressing maximize again). This problem can be seen in the demo as well.

I would have filed a bug report, but I couldn't find a bug tracker for ckeditor, so I decided to post in the forums instead.

But if you call the context menu, the cursor is show. This may help for fix.
Thanks!
I'll use trac for reporting bugs from now on. No idea why I couldn't find it last week.
