I downloaded the program Beachball, to change your wait cursor. Anyhow, the installation 'failed' for whatever reason, but it (luckily) backed up my CoreGraphics. Anyhow, as soon as that failed, I didn't really pay much attention to it until Iclicked on one of my hard drives and noticed that there WASNT ANYHTING IN IT ANYMORE. I panicked, but lo and behold, Get Infol said the drive was still half full. Anyhow, I quickly replaced CoreGraphics, and then the icon disappeared! I then restarted and ran Disk Utility form the Jag. boot disk, and it said the drive was OK. So I restarted and it was back to normal: phew. Anyhow I thought everything was OK until I just tried to remove something from my Dock, it wouldn't let me. Then this happened (this has been happening in all windows, including 'save' or 'open' dialog boxes):
