My game text (specifically map lettering blocks and the entire 'Hotkey' menu are blocked out as white. On the map, from an angle, I can make out light blue (?) lettering but it is extremely faint. When I bring up the Hotkey menu, it's all white and I can not read anything. The unit movement menu displays and works perfectly. I believe it is a purely video-related issue as the commands, both mouse and key strikes, work just fine. You have to know the key strikes by memory since the Hotkey is unreadable. Thank You!
