I run 3 windows virtual machines. Windows 10 plus two linked clones. Everything is good, each VM has it's own desktop space and I swipe between them. They are all set to load "same as last time". When I boot up and resume my machines, they all group together on one screen, each in a tab of their own. This is unbelievably infuriating and another huge waste of time as I spend hours and hours trying to figure out how the heck to turn this off.
