Presently, if you temporarily block an application from the Internet, … one billionth of a second later that application will ask for access again, and you must re-block again. You might have to click Block > Block Only three or four times in a row before the app stops asking. Instead, why not allow Comodo to remember that single-user-block for about 20 seconds (allowing any rapid and subsequent attempts to be blocked, too)? That way, the block remains temporary, yet the effect will be carried out for more than a billionth of a second.
Thanks! Fine product, by the way … especially for free.
