--- Comment #2 from mitterco@hotmail.com 2011-05-22 20:37:10 CDT --- I have this same issue with 1.3.20 for at least two games (Unreal Gold and Serious Sam: The Second Encounter) where the mouse moves on its own and jumps around randomly most of the time when I move it.
Reverting to 1.3.19 fixes it completely.
