need help with loadpano action

hello everybody

first of all: i'm not a web developer and i don't know anything about programming and scripting, i'm simply a 3d designer trying to make his project work correctly.

this is the project i'm working on: link

and this is my problem: i'd like the home button to reload the whole scene from the beginning. the home action button now has this code:

<plugin name="home" align="bottom" crop="0|0|65|65" customColor="true" height="prop" keep="true" onclick="openurl(index.html,_self);" onout="" onover="" onovercrop="0|65|65|65" url="virtualtourdata/graphics/menu/menu7.png" width="40" x="130" y="12"/>

i tryed the loadpano command in the onclick field like this

onclick="loadpano(virtualtour.xml);"

but when the scene reloads, the hotspots in the map disappear, so the only way to make it work is reloading the whole webpage with the openurl command: i don't want to do this, i only want to reload the initial view... any idea?

thanx for help
