Hi, What is going on with v12/Windows 10 and multiple displays? It used to be Windows would extend from the Mac and to my monitor that I added. Now Parallels does some odd "tabbing" and Windows 10 thinks I have 5 screens. This did not start until I updated to v12 of Parallels. I also find when I am looking at program that are minimized to the task bar and I get a preview, it is VERY laggy - especially when I have multiple Remote Desktops minimized (as I often do for support).
