You must do a 'Full Regen' of the Web Orbiter as described in the Wiki page - a reload router alone is not enough. It was the regen on re-boot that corrected the problem...not the reboot itself.
As I wrote "I did several full regens of the orbiter." - so that did not help - I have no idea why not. But what the heck

now it works

Aah, and the N770 size helped
a lot - now the screen is filled and things look better. Still the scroll buttons in video/audio list is a little small - that is not so nice. I will try and find a good skin.
What skin is used on the N770/800/810 ?
And if I should find time (in a couple of moths) I might have a look at how complicated it is to build a new skin. or rearrange one of the existing.
Is it possible to have a bigger font that is better readable in the video/audio list ? How complicated is it to change that ?
