minor graphics oddity TS:JC

[Hentzau]

Patched to 1.1.1 I've got a TS:JC minor graphics oddity with an nvidia MX420, drivers 81.85, bit depth set at 16. The problem is that shadows lighten any area they fall on instead of darkening the area. Just thought I'd mention it as it might be something you'd want to look into. Never saw that happen before in a game. Not a big deal for me. Thanks!
