Only issues I've seen with Zonealarm are: Can be a squeak to setup with AH the first time, however someone posted in another thread an easy method.
It can cause frame rate stutter on 3dfx cards.
Not seen this prob on current nVidia cards.
I have only had other game issues with ZA and Papyrus racing sims. GPL and Nascar4 won't work online with ZA running. All the other games I've tried online, Quake3, UT, counterstrike all worked fine thru ZA.
Otheriwse its great +)
