Just yesterday installed this cool editor. But I guess this is a bug. TinyMCE that was installed by default has gone but the buttons Visual and HTML has been left.
When I click to the Visual I have all ckeditor's buttons, but in the HTML tab I have nothing and I guess we have no need in this tabs, cause ckeditor already has a button called Source on his bar.
The second problem is that in my WP (I don't why) by default, when I open editor the HTML tab is active. So this tabs only disturb all. How can I cure this problems or just delete these tabs?
