I am using three desktops on my Mac-- one for email/calendar and other programs I use most often. Another for web news pages. Another for social media and such. When I boot Finder, it seems to open only in one particular desktop. Would like it to open in my "middle" desktop. Is there some way to get it to open in a particular desktop? Preferences does not seem to help. I can always move icons around so that Finder opens up in my most commonly used desktop. Thanks.
