I have my setting to only show me 4 star ratings.

I am getting a "false" on the bug report, but cannot figure out if I have a firewall or not. When i go to my network connections, properties, advanced there is nothing in there about a firewall. I do have something on there called a Packet Scheduler. It controlls network traffic control, including rate-of-flow and prioitization service. Could that be what is making me have this problem?

Thanks,
