Added a simple ning app to my sandbox network, each view frame has no content:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><title></title></head><body></body></html>
I am noticing a pattern. Seems that when I change tabs while a makeRequest is in progress, I get into a state where the Gadget window gets empty HTML-s for a period of time.
