Hello Fellow FW users: Been away fishing in other lakes. I now have 2, paid 3rd party FW licenses. (not used at same time!!!) The latest is Outpost Pro FireWall Pro 2009. I'm working with it for about a month now counting the trial period. Very interesting product. The older one is OnLine Armor Paid (excluding the AV) which has been posted on here a lot including the learning thread. Now I have zero interest in posting product OP vs product OA on this forum as they are always counter productive. We all know that. What I would appreciate is if Stem or someone of similar expertise could tell me how to set up a system so it could have 2 windows xp sp3 os partitions. They would be identical in every respect except 1 partition would use OP Pro FW 2009 and the other would have the latest OA release. I would then flip between them to report results. FWIW, there are a few posts about Sandboxie incompatibilities over at the Outpost forum as well. So it may very well be that Sandboxie is out of step with latest versions of these top ranked SW FW's. But as I don't need a Sandboxie I don't know from first hand experience.
