Hello,
I used this code a while ago to open an external URL.
Code
<hotspot name="spot2" style="skin_hotspotstyle_R" ath="94.824" atv="0.761" onhover="show_tooltip('naar boven - monter')" onclick="looktohotspot(get(name)); openurl('tour_2.html',_self);" />On my computer it works perfect, but when I upload it to my server I got an error..
Code
WARNING: unknown action: load_thumbnails
WARNING: unknown action: load_thumbnails
ERROR: loadscene() - scene “null” not foundSomeone knows why ? 
EDIT : sorry, I've found it. it was a setting in my hotspot code
