Since I installed VW 2018 Service pack 2, I am unable to run VW on a second monitor - I have two different monitors I have tried this on. My old copy of 2017 still works fine on both monitors. I reinstalled Service Pack 2 but that didn't help. The menus look fine although I think they are not running native resolution on my 4k monitor. Anything in the drawing window is messed up and untouchable. When I grab the top and move VW back to screen 1 it works fine. Then when I move it back it stops working. All other programs including Photoshop and Sketchup work fine on the second monitor. The screen shot shows the drawing window in which current drawing is partially opened in duplicate - this is typical. hardware is super powerful - new Xi laptop with GeForce 1070.
