or you could do the keycommand that has been around since before the performa, command, control, power key... called a warm-boot.... faster and more effective, doesent work in a kernal panic tho... atleast i think it doesent.... there is nothign really wrong with battery pulling, its just dangerous in that you have to move the machine while dong it so it runs a risk of hurting the harddrive, which shouldnt be doing much while you are frozen anyway
