I've been using ZA free version for some time but something weird has occured with it recently - for some reason it appears to shut down while initialising.
I upgraded to zaSetup_92_057_000_en.exe but the problem persists.
After starting ZA it appears to start normally (the Z icon appears in the system tray), but shortly after, and before it appears to have fully loaded, the tray icon disappears and the entry for zlclient.exe disappears from Task Manager.
However, Windows Security Centre says that ZA is the curently running firewall.
I'm using WXP SP3.
