Hi all. Again, keep in mind that I've been a Mac user since 8/11/2007... Ok, I bought and installed a game for my daughter called, "Didi & Ditto" and when she's playing it and about 30+ minutes into (not a set time every occurence), the game screen goes blank. I can alt+tab to see a list of open programs so I know the monitor isn't sleeping but when I try to get back into the game, I can't. The screen is just blank but you can interact with the game, if that makes sense. For example, if I hit ESC the game asks the user if you want to quit. I have to click around on the screen to find the little character nodding up and down for "YES". Keep in mind that the screen is blank until the game closes. Any thoughts on this?
