I've been playing with this game (hex) using six through many revisions. It now appears that the latest version has been hard masked. I wonder why. I don't see anything wrong in its function, even under KDE 4, although it does not show up in my menus without help.
It has not undergone an upgrade in a few years, but it was still entered in the Computer Olympiad in 2009. It didn't win, but made a fair showing. -- Kevin O'Gorman, PhD
