On loading the basic demo page I see a strange behavior of the toolbar.
It starts with a full set of icons. If I then select all (ctrl+a), the icons for type, bullets and select button disappear which I don't understand - if I can press a letter I should be able to create a bullet.
If I then press delete (clear the document) the bullet icons are missing, it seems they are often missing on the first line but I have been able to bring them there by creating a bullet on the second line and then deleting before it. That created a strange state, a line with a bullet but the bullet icons missing.
If I clear the document and then insert->horizontal rule I get a strange state .. most of the toolbar is gone, there is no cursor, pressing a letter will replace the rule with the letter (as if it's selected ?) and the other buttons also have unexpected behavior (ie choosing insert->rule again does nothing).
any help ?
Two side notes .. removing buttons from the toolbar in response to state changes creates a strange and distracting experience, it is much better IMO to have the full toolbar always on and just disable buttons which are not relevant to the state instead of hiding them, or at least have an option for that.
also the way the editor itself grows and shrinks with content is strange and unusual. One expect the editor frame to stay constant with editing.
