Give the OA free version a try-either the public beta of 3.1.14 at http://support.tallemu.com/vbforum/showthread.php?t=6706, or wait a few days to see about the next public release. There are usually more issues with the first public release of a product like 3.0.190, but the extensive beta cycle has certainly shaken most things out now. Haven’t heard of removal problems, but could be with some configurations. I remove it and reinstall it regularly as a beta tester. Also find that OA is very quick with fixes and help from the actual developers as well as the volunteers. Important thing is to find a firewall that suits you, though, and what you think is important, and Wilders is usually a good source for commentary.
