Dual Monitors

[Vhenem]

I've done a search, but haven't seen anything quite like what's happening.

I'm running EQ in windowed mode, and whenever I try to use dual monitors, the screen in game gets quite dark, as in my halfling druid has vision like a human, blind as a bat.

Changing the gamma does nothing, and I have tried Wineq as well with the same results.

Any Ideas ?
