Sanya, Quarant, Hara Taiki: Thank you so much! Not only did your "fix" solve my corrupted System Preferences graphics problem (using a 128 mb FX 5500 PCI) but it also stopped my "About this Mac" from crashing. [bTW, I'm running 10.5.6 with the Voodoo kernel on a very old Dell GX270, SEE2.] I would add that I downloaded the 10.5.5 update from Apple and used Pacifist to obtain and install the CoreGraphics.framework pkg as you instructed. Thanks again!!! You are truly gifted people!
