Every time there is a screen change you have to ALT/TAB away from the game and then clich on the menu bar to re-enter the game to see the new screen. I have got this game working in WIN XP by downloading Microsoft's Virtual PC 2007, it's free, installing WIN 98, and then installing the game on the virtual pc & running it. https://www.gnu.org/licenses/lgpl-3.0.html
