Yesterday I restarted my PowerMac G5 (dual 2.7Ghz) as normal. When it rebooted my system wouldn't respond to mouse clicks. I can move the pointer around the screen and the system even responds to mouseover events (e.g. the text when you move over an application in the Dock) but it won't respond to clicks. Funny thing is, I tried VNCing in from another computer on my LAN and clicking DOES work from there. Any ideas guys? I've taken the obvious step of repairing permissions, to no avail. I'm using 10.4.10 and wasn't doing aything unusual or stupid beforehand as far as I know. Thanks!
