MoW seems promising but my french is just too rusty, so i will wait for the "english" version when it comes out.

Yeah problem isn't with keyclone nor Wine i think my setup just is crappy since when i launch multiple instances in Wine it always show me as 2880x900 desktop ( i run 2x 1440x900 LCD panels ), so it's probebly nvidia screwing up on the twinview.

And running 3+ makes the Xserver crash as it seems.
