Well i have given up trying out Bufferzone.It seems from many posts on other forums that they have rushed its release as it seems to conflict with just about any other firewall or security software resulting in Blue screens of death or endless Preparing your desktop messages and thereafter black screens of nothingness.The only way i could get this to work without conflict was to use it on its own..and windows firewall that aint happening layered security is the way.. Tried various combos of Cis and Bufferzone, disable sand box in Cis make it trusted disable Firewall in Bufferzone ect ... the list goes on. Finally found out that after the beta testing Cis is incompatible.. from Trustware itself.Did some testing with Avast on a spare computer disabled its sand box excluded this and that.. blue screened.
I was never going to drop Cis... not going to happen, just thought as Cis Sandbox had had some bypasses, maybe Bufferzone would have beefed things up...not worth the hassle at the moment.Have found out that Cis and Sandboxie play well together... now,theres a thought!!.
