I’m posting this to make sure you’re aware of a problem with the “Show Ruler” menu item:

Note that the ruler is visible, yet “Show Ruler” appears on the menu. Selecting it will hide the ruler. It can also happen that the Hide Ruler option appears when the ruler is not present.
I’ve also seen that menu option be inappropriately grayed out.
I don’t have time right now to investigate this further.
