"Fixed NetworkStatus bug causing freeze for some, added an off-line attribute to the WorldWind class to elect not to use the network, added a show-network-status attribute to StatusBar".
And from a post related to offline mode issues:
"I've also added an off-line mode attribute to WorldWind for apps that never want to contact the net. Just invoke WorldWind.setOfflineMode(true)."
I updated my previous post about 0.4 - was it yesterday?
