I don't know which version you are using, because the ZoneAlarm I have installed doesn't have that vulnerability, and even on ZoneLabs' web site, they give instructions on testing Leaktest, in which you rename LeakTest to an authorized application. And Steve Gibson, the author of LeakTest also says that ZoneAlarm doesn't have that vulnerability. He also states that ZA is the only one without that vulnerability out-of-the-box (although Norton has responded that they will fix this).

And unlike Craig, I have seen ZoneAlarm on 7 computers, with various OS (Win98, WinNTServer 4.0, Win2000Pro) without any problems.
