no the banner will keep on showing, unless you manually takes it out (disable it)
this option:
Banner filter:
Hide this banner after the user have clicked on it
will make it posible for you to TEMPORARY disable a banner for a ammount of time (cookie based) - it is only disabled for the user, witch have clicked the banner.
The time the banner are disabled can be set in:
Inactive click time:
Number of sec the banner becomes inactive after a user click on it, if banner filter is enabled, the banner will nor show in this time
So setting this to a high number, will disable the banner for a time, but only for that specific PC/user...and only if the user click on the banner...
to acomedate, what you are asking for, you will need to modify the banner SQL found in page_header.php
