For a number of years I used AtGuard, an abandonware firewall from 1999 or so. It had its own dialog when something came up, with four choices:
- allow this now
- allow this from now on
- block this now
- block this from now on

If you chose one "from now on", another dialog would come up to set details of what is "this" - whole website/IP, port, application, protocol (TCP/UDP/both), time of day or any combination thereof.

Now why would Microsoft have to ask me the same question seven times is beyond me. Last year, during the few weeks when I tried to live with the Vista, it seemed unable to memorize the rules I set. Or was the rule that I'd have to answer stupid questions six times every hundred mouseclicks?
