Hey yer i got that problem on my family computer, i got XP installed on 3 of my computers and only 1 seems to have this problem. As i am currenly away from home i havnt had time to fiddle with it but the way i have told my parents to shut down is using task manager. Possibly check the shortcut in the windows system file is working correctly. I dont think it would be anythin to do with settings in XP as it works fine on my other computers, i think a fresh reinstall will be the option i take when i get home, seems easier than messing with settings, good luck neway !
