Choose any app in computer security policy -> edit -> protection settings.
Set any switch (e. g. process terminations) to "yes". Add any exceptions by clicking "modify" (e. g. windows system applications group).

I can verify that this also happens for me with v3.0.16.295 on x32 XP SP2. This was not a problem in v3.0.14.276. I'll be sticking with v3.0.14.276 until this is fixed.
