hello.. never ever listen to richard urban.. he is full of urban myths..
what you are seeing is the display adaptor driver turning down the
brightness...
I dont know why its happening to you but I simulate that exact thing *dark
surrounding but bright cursor*
if I go inside the settings of the dispay adaptor and change them...
I even have a small program called volumemouse that lets me turn the
brightness up and down
with the scroll wheel.. when I turn it down .. I see that exact thing as you
are describing.
what kind of display adaptor is this? nvidia chip?
