Bug 123 Report 4030:
Minor thing I've noticed - if I quit the game, at the "Hit <Enter> to end."
prompt, if I close the window rather than pressing Enter, I get the following:

Bug 138  - #H4045:
 "nethack -s" leads to "-s is not supported for the Graphical Interface".
 That's wrong.
 (The Graphical Interface comes with "nethackw".)
