It seems that a lot of the problems are not so much 'Bugs' in using after the upgrade, but the inability to 'Upgrade' correctly in the first place. My box now appears to need to go in the bin!
Unfortunately all went well right through to the Lollipop sign coming up and the MyGica Logo loading, but then it did nothing more and I now appear to have a box which does not work and I can't access anything to try again. It seems no applications loaded and I gave it half an hour or more! Looks like I now need to put the box in the skip, which is what I had to do with the last one because it decided it would neither connect to the Internet by WiFi or Lan cable! Very disappointed! Ray.
