Hi Piotr
thats somehow what i did.
the problem is that when i read the hotspot.count in the for loop i get a different number than i actually have.
so when the for loop is running, it sets the visibility of all hotspots (hotspot1, hotspot2, ..., hotspot7) to false, even though i only have hotspot1 until hotspot4.
therefor my browser crashes when it tries so set those last 3 hotspots (hotspot5, hotspot6, hotspot7) that i don't have to visible=false...
