Pat,
Thanks for your prompt replies.
I reported this false positive to Zonealarm. And then following the link in the previous thread you mentioned, I downloaded patch 2.17.01h and it restored ptrack2.exe to its proper place. Here's the direct link for any other Zonealarm users having trouble with the newest patch:
archives/PT2/viewtopic.php?t=20594Zone alarm did not complain during this install or when I opened PT. Everything seems to be running perfectly again. (I'm mining two tables and running Pokerace HUD smoothly as I type this.)
Two versions of ptrack2.exe are still hidden away in Zonealarm's quarantine limbo (I installed the newest patch twice. ;- ) but they can stay there for all I care.
Always,
Wiles
