Hi, I just try the Look 'n' Stop and having some problems. Previously I was using OP firewall but due to my computer is getting slower and slower so I was thinking of using LNS which seem to be much more lighter. Please help on my questions below: 1. When I have rules activated when a program is running, I found that the rule will become disable again after sometimes which means that the connection is being blocked again despite the application is still running. Why is this happen? 2. How does the blocking is being processed? I have a program PingInfoView which will ping website. Despite it is being blocked in the application filtering, but it is still be able to successfully making the connection. This make me wonder how the program is able to do that? Is it a bug? Thanks.
