Question "Melih"
Are you (dev team) Working on upgrading to Windows 7?
I know Win 7 is still in beta mode but I am testing It in both x86 and x64 versions, and I am still finding problems with the Firewall part of CIS, Mainly in the outgoing type of connections (firewall leak tests). My possible suspicion is the IPV6 layout in the system.
I'm sure any problems in W7 will be fixed, although I would think only after W7 goes final..
