I assume by 'no user interaction is possible' you're talking about redraws and
touch input
handling, not the UI (non-OSG buttons etc) in general?
It probably is intended behaviour, depending on your usage. As I understand it,
checkNeedToDoFrame() must only be used when running with the on-demand run
scheme. In
this case it's your responsibility to set the redraw flag as required by calling
'requestRedraw()' whenever your scene changes (or anything else of interest).
