two days ago my win7 task bar turned light blue from light gray, the background looked darker even though its black. the icons look faded [no bright colors I.e. red], web pages are dark in color no brightness in color , blues and yellows still show, like in most places it was very hot over the weekend, I did not make any changes to resolution, color initially. my monitor is 6 yrs. old and my video card is a radeon visiontek 4850 which I bought brand new when they came out. any help would be appreciated. thanks. mlmassie
