Using an automatic movement with this code
<action name="pan">
oninterrupt(break);
tween(view.hlookat, 180, 10.0, easeInOutQuint);
tween(view.vlookat, 5, 10.0, easeInOutQuint);
tween(view.mfov, 60, 10.0, easeOutQuad, tween(view.mfov, 60, 10.0, easeInQuad));
</action>
should make it possible to click in the pano and take over panning but it does not.
