Thanks for advice, but your recommendation doesn´t solve my problem. Look at the video on the left. When virtual tour contains more levels (black strip in the right bottom corner with numbers 1, 2, 3 ..) we can observe two konflicts :
1.When virtual tour contens 2, 3 or more leveles, is not possible to click the symbol for language changing. Normally, we can see only one flag.  Afte moveing of curson to this flag, otheg flags apear. But when ai want to click to change language, When I move curson from one flag to other, the arget flag dispears.

2. when virtual tour contens 4 or more levels, symbols with flags are covered popup stick „LEAVE A COMMENT“ (openning from the right).
