I seen some virtual tours where it doesn't appear – for example www.tugendhat.eu/tour/tour.htm – even is there used another plugin it shows there should be some solution.

Hi Alex, thanks for great plug-in. Everything works well, but I have two design issues: 1) There is blue frame around pop-up window. This frame doesn't appear on iPad, just on PC/Mac and disappear when I click outside the window. 2) There is thin light grey line on left side and top of embedded image. How to deal with it and remove frame/line? Thank you.
