You can't really fork on WinXX anyway, though cygwin can emulate it if you want to go that way. For my part, rather than forking off the child process, I'd be inclined to make two fully independent processes and connect them via a socket or a named pipe or whatever. I suspect (others would know better) that an OSX child process may not have the right properties to generate its own windows etc., and this may be what is afflciting you. If you do it voa two processes, the OSX and WinXX versions ought to then work. maybe!
