Spinning Beachball

I seem to be getting a lot of spinning beachballs lately.

Sometimes it occurs when I switch out of PanoX to another app and then return.

Other times, just jumping between windows within PanoX will cause the spinning beachball.

Interestingly, right-clicking on the PanoX icon in the Dock will show that it’s “not responding.” But, if I click on the app icon, I can still jump between windows … I just cannot do anything in Pano X

Additionally, this time the “Edit” menu is “enabled/highlighted”, but without showing the menu items in the edit menu (see screenshot)

What kind of data/logging/info would be helpful in debugging this state?
