I'm new to openlp, trying to evaluate it on my Linux Mint 19.3 laptop. If you select a song and double click to display it, it may or may not respond to the ESC key and return to the openlp window. On several occasions this doesn't happen I cannot get back to my normal windows. The only ways out are either reboot, or at least restart the session using CTRL-ALT-BKSP, or to login remotely and kill openlp. Is there a better way to get back? Switching desktops shows the switcher, but openlp display stays on screen.
If I plug in my TV as a second display, and setting display 2 avoids the problem, but is a nuisance if my wife wants to watch something else!
