- run lgeneral in windowed mode
- play a scenario
- at the end of the scenario, the result is displayed (e. g. "Axis Major Victory")
- confirm it by clicking on it
- now close the window either with the window decorations using the mouse or by hitting a close shortcut (usually Alt+F4)
Another result is displayed, maybe differing from the first, and the program hangs completely. The only way to quit is by forcibly destroying the window or sending SIGKILL or an unhandled signal (like e. g. SIGUSR1) to the lgeneral process.
