Open Editor and click Edit à Preferences à General
Then check the box “Allow Floating Documents in Full Edit Mode”
I have checked the "Allow floating documents....." box to no avail. (closed and reopened program too.) Also I don't understand what working in Tabs means, though perhaps I am because tab makes the side boxes go away and reappear, but sill no minimize button. I am so frustrated!!!!!
You may also need click the top menu to dock and undock the windows.
Window à Images à Float All in Windows
Window à Images à Consolidate All to Tabs
Also if you have one or more images open you can tile and cascade and use the layout dropdown menu (top left of the screen next to the blue icon)
Just to add to what 99join said , the minimize button in the images opened in the workspace is only visible when they are in floating mode. Go to Prefernces>General" and check "Allow Floating Documents" option and then bring any image in floating mode. Then you will be able to see the minimize button.
