I don't know if this is related, but I have a intermittent problem where the widget goes blank/white when I click on anything. I have to refresh several times before it jumps me back to the Home Screen, where I can try clicking again. Sometimes I have to repeat the above steps 5 times before it lets me see my tasks or get to settings, or add a task. I'm using OSX 10.41 so maybe I should upgrade?
John, thank you for the secret mac trick. I will try that tonight. Maybe it will make this refresh problem more bearable.
