I am using a wireless network throughout the house
The MAC is the worse. It will work after a reboot for a bit and then it will not work at all. The house rules show but it doesnt' block the sites or record the activity. I have had similar issues on the XP machines.
I have 3 user accounts setup (3 kids)...and they appear to be assigned correctly.
NSM 1.1.0 for the Mac is not compatible with Snow Leopard. NSM 1.2.0 will be fully compatible with SL, but will not be released until just before Thanksgiving. Because all Norton Mac products share several components, we have to release updates for SL to all Mac products simultaneously.
