In Safari (on mac and pc) the description window is not showing up when I click on the hotspots. It is ok when not in fullscreen mode. All other browsers, it seems working fine.
Safari 5 and 6 doesn't display HTML5 plugin as Description, FloorPlan, PanotourMaps, Viewers into fullscreen mode. It's a Safari issue on fullscreen which can't be corrected. Safari 7 remove this issue.
