Multihead in Torque

Multihead (running an extended desktop over multiple monitors) has become a required part of my computing experience. When I downloaded and ran Realm Wars (Win version) it crashed when I had more than one monitor enabled. When I disabled all but one monitor, it ran. Is this a problem with Realm War, or is the Torque engine in general incapable of handling multihead systems? Support of multihead does not imply that the application should run on multiple monitors at once, just that it should run on the primary display while the other monitors are active, without crashing.

Thanks,
Mike
