Mouse doesn't work?

[Radiant]

One player of Heroine's Quest reports, "In game when I move the mouse, it stutters then shoots off in one direction. Anyone know why?"  This person is not using Logitech Setpoint. Does this issue sound familiar to anyone?

Could be problem inside Allegro, for instance.
We were reported mouse lags in certain Linux enviroment:

This is not Linux though. So far this is the only user who has reported this problem; it seems to work fine for most people.
