Found a new bug !
just spent half a day messing around with my code and testing your sample code just to find that the
Editor1.DisableItemList = "InsertTextBox, InsertInputSubmit, InsertInputReset, InsertInputText, InsertInputPassword, InsertInputhidden, InsertListBox, InsertDropDown, InsertCheckBox, InsertRadioBox"
in the page_load sub messes up the postback event.
Not very happy
