About one quarter of my Metro apps show the loading screen and then load up a blank dark-blue screen. I cannot click on anything and the right-side menu shows but the menu items do not work. Apps like Google Search, Hulu Plus, and OneNote are doing this. I have already tried uninstalling then reinstalling to no avail. Any ideas?
Please run the Windows Store Apps troubleshooter:
and look if it can detect and fix issues.
Here are also some information on how to fix issues with apps:
