In previous mail i posted this bug; The default point style / hotspot shows sometimes no target panorama, only empty window. (under action parameter. goto a panorama or group)
I think have found the reason for this. This behaviour only with 1 hotspot in the panorama or when clicked on the 1st placed hotspot in a panorama when there are more than 1. When a second hotspot is placed both work good. But the 1st hotspot never shows a target panorama when it is clicked as the first one.
With 2 hotspot in a panorama always the second placed hotspot must be clicked first (it shows target panorama) and the 1st placed hotspots works also after that (shows target pano)
So directly clicking on the first placed hotspot gives a empty target window. I tested it with a mini tour and this behaviour can be repaeted.
