Carentan

I use a Matrox G-400 card, supporting two monitors. When I start the CM demo with dual-monitor support enabled, it defaults to screen 2 and my mouse will not activate any of the 4 opening screen buttons. The only way to play is to deactivate dual-monitor support and reboot with just one monitor active. Is there a workaround for this, cause I'd really like to be able to play AND daytrade my way to riches?
