to tell you the truth I had the same trouble some time ago!
Then I realized that was only something like a "scene refreshing" bug, I mean the player didn't update the display after you clicked on the requested direction but if you hold the mouse button and drag (in order to explore the panorama) you get the requested update.
Maybe this can help you...
BTW Merry Christmas from your Italian friend...
