Just tried safezone again, at least on win7 it seems to open soem webbrowser. and then your complete stuck.

-No window mode
-No easy switch back to desktop and back to safezone to get information or read things that you need.

The only thinmg its doing right now is giveing annoying screen in my webbrowser.
Make at least safe zone easy switchable between desktop and safezone. then i maby would use it.
Now its more a threat to use it because you cant do anything, So not sure whats the use then.

Until switchen between desktop and safezone is made easy and fixt. its time to disabled it until then.

Edit:
i see you can link a shortcut. thats not good just add button to the safezone and make it windowed so you can have your other information next to safezone. dont do it like window 8 modern UI that you kick very fast in corner to.
And how can you disable it in the webbrowser. the banner is terrible annoying.

Edit:
For people that want to get rid of the safezone banner spam on many webpages
