I'm baffled by this one. As you can see in the attached screenshot, the stripes in my windows are now pale green, not the light blue they should be. As shown, when one window overlaps another, part of the stripes ARE blue. What is going on here? This is on my iMac 24" 3.06 running 10.6.3. It's been doing it for a few months but doesn't look to be related to the yellow tint problem I see people having. Any help would be greatly appreciated. Thanks!
