The second screen is a different resolution from my primary screen. But other software and DAWs don’t seem to have problems with that. Maybe something in the “coding” of WL is different. The more complex WL becomes the more problems it seems to have. I guess that is normal but not welcomed. My life was much more “simple” back in the days of WL 6.0, WL7 and WL8 were disasters (IMHO) and WL 9 was very stable after WL 9.5.5 and then we got WL 10 with all its problems. Hopefully it will all get worked out. I am sticking with WL 9.5.5 for the foreseeable future. FWIW
