Under WinXP SP2, I tried OA free (184.108.40.206) and Sandboxie free (3.22) with ThreatFire 3.0.14 (free). When I clicked on the Sandboxed Web Browser shortcut on my desktop, I got the unpleasant 'debug' window. Apparently, there is a conflict between ThreatFire and Sandboxie. I use Firefox 2.0. - Any particular settings (rules) I have to make inside ThreatFire to avoid conflict with Sandboxie?
