NOF does not respond

Hi

 

I'm trying to use NOF to block gmail on my son's PC,  but I want top allow the use of google as a search tool.  Even though I've blocked mail.google.com and gmail.com, my son can still get to his gmail account.

 

I thought maybe this was because google.com is allowed, so I put google.com on the black list too, but he is still able to access both google and the gmail sites. It's as if I hadn't even blocked them! What the heck is going on?

 

BTW, I also have checked the box for blocking webmail applications.

 

thanks,
