Double click menu bar does not fill screen with application
Using Big Sur on iMac 27". Previously could double click the menu bar the application would grow to fill the available space with a menu bar and dock still visible. Now double click does nothing. I read the previous mentions on this subject and tried all the different switch settings but none worked or restored the functionality that existed previously. Does anyone have any tips or tricks to get Bug Sur to behave as previous OS's did?
iMac 27″, macOS 11.6
