I have a (managed) user account set up for my 6 year old son with time limits. I limit him to 30 minutes M-F and 60 minutes Sat & Sun. Ever since I upgraded to Snow Leopard the time limits don't seem to be functioning e.g. it doesn't tell him his time is almost up and it doesn't cut off his usage. I've even gone so far as to blow away his user and set up a new one and it doesn't seem to have helped. It still doesn't recognize time limits. Anyone else having these problems? Any ideas on fixes?
