I've recently installed the Loki version of Railroad Tycoon 2 for Linux, including the latest online update, but the sound volume is much too loud. The README says that I can adjust it via the Game Options window, but I can't find any such window by running the program nor can I find any reference to the Game Options window in the manual. Does anyone here know how I can adjust the sound level, other than changing it for all applications (not a good solution)? Paul
