New 11.3 install and working the wiggles out one at a time. If I minimize a window on the desktop it just disappears. Any and all open windows. Can't figure out how to maximize it again. They still active somewhere because I have to kill it (crtl / esc / kill process) to close Firefox and any other windows regardless of the application. Where are they going and how I do I modify this behavior. Relatively new to KDE and navigating is still an adventure.
