I understand you can turn this particular security setting off.
Which kind o defeats the purpose doesn't it? I think I saw a MAC ad that went along similar lines.
You did see the ad, it's one of the funnier and probably truer of the series and yes, turning it off defeats the purpose. Unfortunately, running any security at too high a level will interfere with how programs run and the intrusiveness of messages. Like just about everything in life, there are trade offs.
