In this video I am going to take you through what I did to stop Maya 2018 from hang crashing when dragging any window (especially UV editor and hypershade) on to second monitor window.
I have an Nvidia GTX card , which doesn't seem to be supported.
Go in to your Prefs, change from OpenGL to DirectX 11
And go in to UI elements and turn of save and restore from file.
Full details in the video.
Hope this helps someone.
Cheers!
