Dear Klaus,
I think I found a bug in the newest version of Krpano, when using little planet view in HTML5 desktop, hotspots with depth attribute just behave as if they had some "flying". Krpano 1.19 Pr3 is working good with same code.
Turn little planet view and check both icons in following example: http://imagen360.com/krpano/depth-hotspots/ left one is the one with depth, other one doesn't have this parameter. ¿Is something wrong with the code or is a bug?
Right now this is affecting a tour so please help us with this.
Best
Luis
