V3 and remembering application rules

I am having problems with v3 remembering my application rules.
This is for winvnc.exe

I have allow and log all tcp into and outta my computer.
I have my work IPs setup also in the same manner.

This way I can access my computer from anywhere in the house on other computers and from work.

Problem is that every few days Comodo goes stoopid and will block all ip and ports for winvnc.exe
Nothing can get in. Even my local network is blocked (:AGY)

Winvnc.exe has NOT been updated as far as a new version of the program goes.

What is causing this to happen all the time.
Prior to this I was using version 2.4 and it remembered settings all the time even thru upgrades/
