Hi,
In the firewall rules window, every time I select a rule, after a few seconds (up to a minute), it disappears automatically. Each time a rule is deleted, the rule counter is decremented. If I close the window by clicking on the cancel button and reopen it, the deleted rules are still in the list, but if I close the window by clicking on the accept button (accepting the changes) and reopen the window, the deleted rules are gone forever.
I have tested this on five computers with identical results.
I have uninstalled and reinstalled ESET Smart Security Premium but the problem persists.
Regards.
