Word on PlanetStarSiege is that if you are having OpenGL problems after installing the 1.3 mouse (lag, jittery mouse, etc.), make sure your Windows desktop is not set to 32-bit color. Also, I and a couple of other folks I know have been getting bounced out to the desktop when running version 1.3, and now Sixxo from Insomniax.net sends word with a solution that worked for me: Shadows are not working properly in the new version, so if you've turned shadows on in your ClientPrefs.cs file, you must disable them ($pref::shadowDetailMask = "0"; and $pref::shadowDetailScale = "0.000000";).
