Gamma change?

[Viper]

Whenever I start up AC, or switch from fullscreen to windowed and vice versa, my brightness will always drop from the setting I have it at (140, in autoexec.cfg and saved.cfg) to something quite dark. I have checked the numerical value of gamma upon this happening and see no change from 140.
Yet, when I do

[SELECT ALL] Code:

/gamma 140

my brightness will go back up again. This only happens under the conditions stated above.

I use Mac 10.6.8 Snow Leopard, and have an ATI Radeon HD 2600 Pro card.

This happens to me when I switch from fullscreen to windowed and back as well, though not when I start up AC...

I got a Mac too.

This is common with many graphics card drivers. Many of them have issues just when switching out of fullscreen in any program, let alone dealing with gamma values.

I use windows.
When i minimize the game from full screen then open it again it resets the gamma to 100 again.
I just type /gamma 100 *press enter* /gamma 150, that fixes it for me.
