Color shifts in UT,driving me nuts!

[tex]

The color shifts to about 25% red after UT starts to run.Everything is OK in the setup screen but as soon as the game starts to load ,RED!The Matrox coloy correction utility does not seem to have any affect on 3D modes.Is this normal?Is there anything i can do to fix this?I know this is a small problem compaired to others,shutdowns,hangs,or just not running,but annoying none the less. Any help would be appreciated.Thanks in advance
