What I've decided to do here is remove the 'do not ask again' option from the disallowed process confirmation prompt. It's surely seldom used, and so there's no reason people can't tolerate that extra confirmation. Had that confirmation not been previously checked to 'not show again', probably this issue would have been notated.
Also, I'll see what I can do better notify when disallowed processes are run. Maybe finally bring back system tray tooltips, as I know some users have requested for some time. The issue with them is that, in certain environments, they can quickly become flooding.
