Text entered into a frame text box works well if left and center justified, but if the text is entered in right justified mode, it does not adjust the text within the box when you use the tab key. Text appears temporarily outside and to the right of the frame box until you enter some text after the tab again. This makes it hard to see what you are getting as you are typing. It also does not put the last tab inside the box unless it is followed by some letter, number, or symbol. Also, you cannot leave a space or series of spaces after the last text is entered. When you press return, the spaces do not appear inside the frame box.
The same problem existed in PagePlus X9.
