Hello,
recently I work on a project which needs to display artworks in the virtual tour, i put artworks in a layer with the image-mwheel-touch-zooming and dragable-layers funtions, it works on desktop, on mobile devices the zooming funtion works but it can't dragged. view the project at [url]http://www.cnvtgo.com/zjmsg_revised3/
it's done by krpano viewer 1.19. Please help me resolve this problem. Is it a bug? waiting for your answer. Thanks very much.
