Created attachment 154661 [details] Tabbed mode When you use 'tabbed or tabbed compact' user interface mode, and you try to unmerge two or more cells (previously meged), merge button gets disabled and unmerge operation can't be done using menu button. if you move to any other user interface mode, button is enabled and operation works.
