In Smart Notebook 23 the menu bar that appears in full screen is no longer functional. In Smart Notebook 22 I was able to use this menu bar with a pen for the plasma screen to select a pen colour or highlighter. This no longer works in Smart Notebook 23 and any selection made with either a pen or finger affects the mouse only. When smart notebook is not in full screen, the ribbon will still recognise a pen or finger selection and allow the pen/finger to be used as selected, but the full screen menu bar will not. This functionality is fully restored when "Open in Notebook 22" is chosen from the view menu, so it appears to be a bug in Notebook 23. The attached screen shot shows the menu which is broken in Notebook 23.
