Brightened Gamma When Starting/Exiting

[MatchLiteX]

This isnt really a big deal but i would like to fix it, for some reason whenever i start up planetside, the gamma and brigtness are realy up but when i just go to video it sets back to normal, and whenever i exit the desktop gamma is really bright, i can always set it back to normal in about 10 clicks so its no biggie, i would just like to fix it, wow thats a long run on sentence:o oh well
