Gamma Slider Stopped Working

[mrozee]

I did a Windows Update today. Yah I know my first mistake however I have been playing P99 for years using dual monitors. EQ runs on one in Widows mode while I watch internet TV on the other during those long boring camps. EQ is run in Administrator mode, I have the proper compatibility setting, screen settings, yada, yada , yada.

Soooo, after the update the Gamma slider no longer works and my screen color is stuck in dark. If I flip to Fullscreen, the slider works but of course if I try to go to the second monitor you have to go back to windowed to get things to work. so annoying.

Anyone have this problem and what was the fix? Help!
