I just migrated my Parallels 10 app and VM (Windows 7) from my old iMac to a new iMac. While everything seems to work ok, when I start up Parallels, I no longer get my windows desktop to appear in a window. I only get an icon in my dock that I click to start running my windows apps. Where did my [Windows] desktop go? I'm running High Sierra, but I don't think that's the problem as I was running High Sierra only old iMAC and everything worked fine.
