Ever since the update to version 6.0.1203 SafeZone has not been worked properly. The screen gets way to dark and still stays dark after I leave the zone on both monitors. I have uninstalled and reinstalled Avast Pro. Uninstalled Comodo firewall and EMET assuming it might be conflicting somewhere. Still no go. Any idea what might be causing the dark screen?
I had a similar problem (though in my case exiting safezone restored bightness) that turned out to be to do with power management (which is logical for screen dimming I suppose).
Do you have a power management utility running at startup - for instance I had acer epower management. Disablng it was a workaround for the problem.
