If it's on ZT1, try this: Click on the disc icon. You'll now see Load Game, Save Game, Main Menu and Exit options. On the right of this little screen are some icons. Choose the 2nd one down, the one that looks like a monitor. Under "terrain blending" make sure you have the "balanced" option chosen. I've had problems with a blinking cursor when I've tried to change this option. As long as I leave it as "balanced", I don't have that problem. Hope this helps!
