No, I don’t… In fact, you know, I’m not an Alwil guy but I can bet not. Alwil team is trying to release the 4.5 version and ZA was recently sold, many changes in both sides.
No, I use ZA free. Sent an email never answered.
Btw, all my emails to ZA support were for nothing 
Yes, you’re right. Can you do this tests and researches…? I think you have the knowleadge and this will help a lot of users with firewall troubles (or, better, compatibility troubles at boot).
Fully agree. That happens frequently when I’ve been using ZA 5 >:(
