I am having this strange "color change" happening after the screen saver has been activated. I move the mouse to close the screen saver and the grayish color scheme (graphite) has changed to a light blue. I then have to go into the control panel and click on display to get the graphite back. No problem until the next time screen saver becomes active. I took a screen shot with "Grab" but noticed on opening the pic. it's the correct (graphite) color - it was light blue when I saved the picture. Any ideas?
