Back doesn't work - new phenomenon
the originally reported problem in this post was, that the back button does nothing when the description of a special tv show is displayed.
Now I observe a new phenomenon:
1.) start IP EPG
2.) after everything is up: press ok
3.) the description of the currently running tv broadcast is displayed
4.) hit the back button
5.) Instead of navigate back to the channel list, IP-EPG is closed :(.
