I can't add bold text to a sentence diagram any longer. I used to be able to double click a word to select it and CTRL+B to make it bold. Then I'd underline with CTRL+U. Not sure when it started because I haven't been using sentence diagramming much lately, but I can't do it now. The text formatting drop down box is live if I don't try to select any text, but if grays out once I do select text.
