It seems plugin[map].pantospot doesn't work while map is id 3d mode.
Look at http://projekty.panoramy-wirtualne.pl/bb, click Uruchom spacer, then expand map panel (right side) and click any thumb at the bottom of screen. By default the map is in 2D mode and all works perfectly (pantospot moves map to proper position), but when you switch viewmode to 3d (3d button at the bottom of the map) and chose any panorama, the map moves to very strange positions.
Have you ever met similar problem?
