Mac users please note that Sudoku is a Windows-only program. Sudoku is not supported on any computer other than Windows-native.
This means that no support is offered when Sudoku is run on a Mac under Virtual PC. In fact, there appears to be an issue when the program is used with Virtual PC. I am a sole programmer (with no Mac, whatsmore) and regrettably I have not had the time to resolve the problem. My apologies to all Mac users.
