at the moment it seems to only support windows xp however its not a criticism of the product but since vista and windows 7 are the newest operating systems it might be an idea.

one last thing, is there a way to put it on a usb flash drive ? since the loading time would probably be reduced by a great deal.
as i said its a great program and i'm very happy with it I've just downloaded the new version and will update it now.
thanks
