I was googling around trying to find a solution so i can play Sins on my Aspire One, and i stumbled across along with these forums, this website:
http://www.virtualsecrets.com/acer-aspire-one-netbook.html
If you scroll down he has a solution for the menu's not fitting, so the game can be playable. I gave it a shot and it seems to work!
Since I found more people asking the same question on these forums, I figured i'd share.
