I have the same issue.
Also sometimes websites (that I have set as my 'default' for the browser - Examples '
www.rottentomatoes.com', '
www.imdb.com',
[Link: bbc.co.uk], '
www.google.co.uk') don't always load. The blue progress bar gets to about 50% then the Philips page not found error is displayed. If the Home button is pressed it seems to load correctly.
