• Game locking up on my Wii U™ console when I hit the ‘home’ button
  
  There is a known issue that can cause the game to lockup when the display output is set to 576i and the ‘home’ button is pressed.
  To fix this issue please download the latest firmware updates available for Wii U ™ or select a lower resolution.

To learn more about the Wii U ™ system updates, visit the Nintendo web site:

Thanks.  I have seen that sticky post.  The freezes I am experiencing are not as a result of pressing the home button.
