The krpano_as3_interface.PLUGINEVENT_RESIZE event does not seem to fire when the viewer is switched to/from fullscreen mode, even though the viewer pane does change size. The event does what it is supposed to do when the (non-fullscreen) window is resized manually.
Viewer version:
1.0.8.11 (build 2010-05-31)
Environment:
Both browser and standalone
