Hi!
First of all, you shouldn't have to be uninstalling/reinstalling PG if you want to get onto the forum while keeping http blocked. If you right click on the PG icon in your system tray you can just disable it (the icon will turn red) . Then, when you are off the forum, enable it again (the icon turns blue & it's back to being a sentinel again!)

I can't help you with some of your questions, I don't use a Mac (I have the other OS... gag, spit...Windo$e). If LimeWire is telling you that it doesn't detect a firewall, this is a good thing! If LW detects a firewall, it's something that is stopping LW from working properly. Like a software firewall that's not set up properly, or a firewall within a modem or router.

You can choose to log/show allowed connections in PG but you can't choose to adjust it's own list of IP addresses to block (as far as I know). It has it's own lists of IPs to block & it will block all of those known IP addresses. I don't know why it would block the LW forum & not other http sites

I hope I haven't confused you too much!
