Magma has a windows NT version..
Not sure if it works on Xp..
but those guys dont do much development with the Windows version..
they concentrate on the Linux versions only..
right, they only provide the windows version for the client(gui), you can open the gui in windows, and connect to the real magma session(server) to do what you want, it looks like you are running the magma within windows, actually it's working on client-server mode.
