Unable to move canvas from main display to second screen

[Perendale]

It seems to be a "full-screen thing."

Using the double arrow top right makes no difference at all to the problem.

The green traffic light however, when long pressed has options (I didn't know that!) and one is move to Viewsonic. That moves the canvas over no problem, and back again. Yay! There is still a weirdness that when moving in and out of full screen locks up the app and I have to force quit and begin again. I'm playing with that to see if I can come up with something repeatable. I'm busy this week so it may take a while.

Thanks Mark! Excellent suggestions as usual. I hope Ambient appreciate the work you do around here (are you listening Ambient? ) because I certainly do. Many thanks to you for the comments and the help both to me and all the other people you have helped and guided over 2023.
