When I go the URL of my tour, all browsers work except Chrome. Chrome loads the tour and crashes. Is there a reason for this or does it need a software fix?
I have tested your link now with Chrome 51, 52 and 53 on Windows 7 and Windows 10 on 3 different systems - no crash in any case, regardless what I try.
There were some reports about Chrome 51 crashing on Mac system in some cases, but even then the problem is somewhere between Chrome and the system and not between krpano and Chrome.
