Fog of War Opacity

[Minethulhu]

When using FGU and LOS, is there a way to adjust the opacity setting for Fog of War on explored areas?

I've noticed that depending on my computers gamma setting the Fog of War for previously explored areas is virtually indistinguishable from the deep black of unexplored areas. I have several players that constantly complain about the Fog of War and now suspect this is their issue, but I would rather not loose my hair while playing Technical Support for my more luddite players.

EDIT
Alternately: I know a number of computer games have a screen that is used to "calibrate" brightness, contrast and gamma. Has anybody put together an image that can be used to do this for FGU?

There is not. We have people that complain that it is too bright that it negates the whole point of lights; while others want it to go away completely. We've found that there is no solution that makes everyone happy. You can click the wish list link in my sig to add or vote on an item to allow it to be customized on the client, so that the idea isn't lost.
