Issue moving Illustrator to a different virtual desktop space
Illustrator CC 2018 v22.0.1
I am using several virtual desktops (Apple calls them Spaces) and I am used to being able to move application windows to different desktops by dragging open windows to the top of the screen, which reveals the available desktops. However, when I try to drag Illustrator to a different desktop the action fails, leaving a transparent grey window over the whole screen. Logging out and back in again clears the grey window. I will try to make a video to show what happens.

Okay, so I've not been able to make a consistently reproducible case yet. I'll test again after work.
