With the latest XAqua 0.3, the -help and -version options have regressed: when invoked with the full /usr/X11R6/bin/X path name, they work as before. When invoked as X or Xdarwin, there is a "Bus error". In both cases, I am doing this in an Xterm under X, but this used to work, and still does work for older versions which I have left in that directory but renamed.
Though it does "Cause crash", obviously this is not an urgent bug. My "Feature Suggestion" is to add some useful information to the message for the interim releases of XAqua - I was only doing this to check which version I was currently running. Just the date of the build was all I really wanted. Put this one on the back burner, and keep up the good work!
