I'm running Windows 8 in VirtualBox (latest version) and it works fine in most respects, however I'm having a real headache with the App store icon on the start page. When I click the App Store icon, the screen turns blue and shows an icon of a bag. It stays like this for around 5-10 seconds and then just goes straight back to the start page. No app store appears! Am I supposed to be able to access it and does anyone else have a solution?
