Cursor disappears after color pick

Starting in Graphics Mode, I used the Colors window to pick a color, by clicking the eyedropper, then clicking somewhere to pick a color. My cursor then disappears. This was repeatable, including after restarting Pan X. CMD-tabbing to another app brings the cursor back. It happens with my form in Data or Graphics mode. Anyone else seeing this behavior?
Mac OS 10.13.6

No cursor problem here (macOS 12.3.1).

OK, the same thing just happened in Nisus Writer Pro, so it seems to be a problem with my OS, not Panorama.

Thanks for the response!
