Hello, For a while now I've been experiencing corruption of the graphics of Finder windows. It seems to be happening after extended periods of uptime (i.e. not sleeping the mac). It looks like this: I've tried re-installing Leopard with the combo updater but no luck. My mac is a Summer 2007 model MBP (I seem to remember they had problems with the nVidia GPU, could the issues be related?). Thanks in advance for any help!  Odd that the corruption seems to be only on the Apple icons and not the one I added (the one on the far right). Also, after a while it fixes itself.
