I tried using the shift key and it did not stop the window from snapping to the size of the screen. I don't know how to fix that.
I also looked thru the options for the taskbar and could not find a way to turn off the preview windows.
sorry strums. I don't know.
I'm adjusting my answer to "Don't be such a tight arse and buy a screen manager such as DisplayFusionPro...... then you can use the shift key to stop snapping"
