Hi Ian, I just test-ran kmahjongg on OSX/CI’s KF5 and it RUNS!!! :-) I can play the game, as you told me to… ;-) BUT, trying to leave the application with CMD+Q or via the corresponding “Quit kmahjongg” menu item DOES NOT SUCCEED!!! The only way to do this is by closing its main window. Could it be that on KF5 some signals go astray? Merry Christmas, Marko
