2018.14. Dual Monitors.
* I setup the screen the way I want it, with the sequencer on the left monitor, house and model previews on the right. All other windows are on the right with the previews.
* Click on "View -> Perspectives" then "Save as New". Give it a name (such as "Dual Monitor".)
* Close down xLights. (Saving when asked.)
* Open xLights.
* Click on "View -> Perspectives -> "Dual Monitor".
All the items that were setup are now on the same monitor, somewhat overlapped.
Nothing I've tried seems to get xLights to maintain a perspective that I set. Any clues would be helpful.
