Accessing the Properties Panel

Sometimes I have difficulty making the Properties panel appear. CTRL-8 doesn’t work, nor does a simple click on the bottom bar or arrowhead. This seems to happen when I have closed all panels with CTRL-0. Is anyone else noticing this situation?

(I can restore the Properties panel–along with the side panels–by typing CTRL-0 again, so I know that work-around.)

Even if you have hidden the Properties panel with Ctrl+0, hitting any of the Ctrl+6/7/8/9 shortcuts effectively undoes Ctrl+0 anyway, so you should always be able to show it simply by typing Ctrl+8 at any point if it is hidden (provided you’re in Write or Engrave mode, of course).
