It's not the most devastating thing, but my Finder bar at the top of the screen sometimes goes black. Thus, it's impossible to see the words and symbols or time. I can click on it and find the pulldowns, but it's nonsense to have to do. Usually it is white on start-up and after a sleep in the day I will get the computer awakening to find the bar changed. Just another sad Snow Leopard glitch. Anyone have any idea how to correct it? Terminal>killall Finder doesn't help.
