Hello,
Sorry to hear you are having issues.
I have an issue where when I'm using youtube on fullscreen (for example), Start8 seems not to function and brings windows 8 menu instead. Is that a bug, unfixable issue?
Please make sure your setting is corrent. I am sure your will be using your Win key on your keyboard, so the setting should be like below
