Hi Klaus,
i find strange behaviour of the bgborder. (OSX Safari and IOS)
http://www.virtualtuur.com/krpano/bgborder/2/
http://www.virtualtuur.com/krpano/bgborder/2/tour.xml
When i click the button in the controlbar, a box appears. (add layer)
When i click the button again it disappears and will be removed. (remove layer)
When that is done there comes a small gap in the controlbar border, left top.
Is that a bug?
Resizing the screen resolves it.
But invalidatescreen(); or updatescreen(); makes no difference..
