I have seen a few posts with users having difficulty with their kids being logged out when their time is not up. I am having the same issues and haven't seen a solution in the Forum yet. Here is the situation:
I have 3 kids with accounts. All have time restrictions: permitted times they can use the computer and a permitted number of hours. For 2 of my kids, these restrictions work perfectly. The third child is having nothing but problems. This morning he logged in at 7:11am and ran out of time at 7:46am. He was not allowed to start using the computer for the day until 7am and has 3 hours. NOF gave him 46 minutes. This has been happening every day for the past few months. We have set up another generic "kids" account with the same time restrictions and that one works fine too so we have had to switch to letting him use that one.
I can't seem to figure out what is wrong with the settings. They appear to be exactly the same as his siblings and the "kids" account but he is still running out of time within the first hour.
