Gadwin? Never heard of that. I do what you hate to do: I just take pictures with printscreen and cut them out in Paint. It is a pretty accurate thing to do, but I never knew about programmes that could make fullscreen pictures. At first I thought it had something to do with the size you're playing in. Now I think it's just more logical that the problem is Gadwin, not The Sims 2 itself. Isn't there something in the settings you can switch?
