It appears that your screen display is not showing the row of buttons which should be along the bottom of the screen, so you’re not seeing the green arrow button or any of the others. You need to choose a different screen resolution. But first—I hope you’re not working on a netbook whose maximum screen resolution is simply incapable of displaying the full game screen. Many of the small netbooks are incapable of running the game at all for this reason. If that’s not your problem, here’s what to do. After launching the game and before starting to play, you’ll be at the Main Menu. Click on Game Settings. At the top is a Resolution selector. Click on the downward pointing arrow to pull down the list of options. Try either 1024x768 or 1280x768. These are the lowest vertical resolution available (768) and should show the full game window on your screen. If you continue to have problems, please reply with technical details on your computer, monitor, and video card so I can help further.
