well.... for starters there hasn't been a leeched or created external hack for WIN7 yet..., besides the ones that are already detected but they aren't external but internal so that's a no-go zone, um i had the same problem as you with the windowed mode so i wanted to ask you did you try running as admin and then getting into windowed mode?....cause it worked for me after ages of trying stuff , but maybe soon someone somewhere will release a hack "external" hack for W7....patience is the key here
