You're welcome :o)

>Thank you for the screen shots (in email). I can see that your version has a very different UI than mine. Since your version is 3 it tells me that yours is more recent. But since I learned how to use my version's network control rules (which is similar to your Network Security Policy, from what I can see on your screen shots), I will hold off on upgrading my version.
>Right now, in the morning, after starting my two computers, everything works fine. So, maybe I will get some real "work" done today <g>
>Again, thank you for your help.

>>Mine is free as well. I think the layout just changed with each version.

>>>My copy is Personal (free) and version number is 2.4.18.184. It must be that the professional does things automatically so there is not need for these options. Just a guess.

>>>>>>>>>Sorry to trouble you one more time. I found that if I Turn Off my Network Control Rules in Comodo, it allows networking to work. So it must be not just Trusted Zone but also something in the Network Control Rules that has to be set up. Can you, please, send me what your Network Control Rules looks like? Mine are all default; that is, I have never changed them.
