I have an Intel iMac, a white one, from late 2006. It's running Tiger, not Leopard. Today it froze after I quit the internet (firefox). I can still move the BT mouse around (and see the arrow moving), and I can still use the BT keyboard. However, I CAN'T CLICK ON ANYTHING. I can't open any folders, applications, menus - nothing. So it's just like the applications are frozen. If I hover over the dock, the dock pops up, but I can't click on anything. I did a PRAM reset, and now I don't know what else to do. I am using a custom icon set like this, but I've had it for awhile. All that required me to do was copy and paste a picture into the 'get info' part of the application, so I'm not sure if this is causing the problem! Any help please!
