I’m sure it’s a setting that I’ve accidentally changed, but when I click in one location and drag the tape measure tool to another location and click again, I’m no longer seeing the little tick mark for that measurement. Any suggestions would be greatly appreciated.
That was it. Guides in View menu. THANKS SO MUCH. It was driving me crazy
Good deal. I expect you found all sorts of guides when you turned them back on.
If you aren’t already doing so, I would suggest getting rid of guides as soon as they’ve served their purpose. I’ve set up a keyboard shortcut for Delete Guides which gets used frequently.
