I use your excellent CIS 6xx. Thanks you!!
In CIS vr. 6xx., the update confirmation pop-up is designed as mandatory option.
I think this is not a good idea, because this pop-up may interfere with others activities, and this is
an inconvenience under some conditions, specially when we need not be interrupted by others messages.
I suggest you to create an option that can be turned off, if we need it.
Thanks again your excellent and complete program!!
In my opinion this behavior is indicative of a bug. I really hope the Comodo devs did not intentionally design it to act in this fashion. My bug report can be found here.
