Disable - Enhanced Interface - Full WYSIWYG Editing
there is a setting Enhanced Interface - Full WYSIWYG Editing
which is dodgey!
I have not yet found a browser that it works reliably under, Firefox, Chrome, IE7-10 all have various issues with it, many of them showstopping. Under IE 10 is won't allow an edit right after post as the js fryies itself, sometimes it stops the enter key from working in the editor.
Can we add something to switch away from this mode if a browser other than whatever obsure point revision it was designed for is detected.
For anyone else suffering from frustrating editor system just go into the page above and change to the old "Standard Editor - Extra formatting controls" which works without the additional frustration.
