Multi Monitor Support is not handling switching setups well
"When I plug ina new primary monitor, move my icons to it" doesn't work
I keep all my fences on my primary monitor, and the settings:

are perfect for me.
Except - they don't work. I undock my laptop and then connect it back to the dock. Now, all my fences and icons are on the second monitor and not on the primary. I disconnect the primary, and reconnect it, hoping that would make the icons switch ... and they do ... for about two seconds, and then they switch back to the second monitor.
Is this a known defect, or is there a setting I am misunderstanding
Thanks
