BOINC 4.25 and Zone Alarm

I just installed 4.25 to give it a go. No data problems as far as I can tell. Just alot of "aparent" internet activity. The thing is, only ZA is showing the activity. Not my the task manager. Background intel maybe? If I set ZA to block it Boinc will crash.I also need to give the sreen saver inter accsess to operate properly. Not that I'm complaining. All part of research.
