Hi,
yes, this is an unexpected behavior of the 'addevent' usage, which was added to the vtourskin.xml in version 1.20.8.
Here another workaround - search in the vtourskin.xml for these lines:
txtadd(layer[skin_map].spot[get(spotname)].onover, 'set(hovering,true);', get(style[skin_tooltips].onover) );
txtadd(layer[skin_map].spot[get(spotname)].onout, 'set(hovering,false);', get(style[skin_tooltips].onout) );
and change them to this:
txtadd(layer[skin_map].spot[get(spotname)].onover, 'set(hovering,true);', get(style[skin_tooltips].onover:addevent) );
txtadd(layer[skin_map].spot[get(spotname)].onout, 'set(hovering,false);', get(style[skin_tooltips].onout:addevent) );
In the next krpano release the vtourskin.xml will be fixed of course.
Best regards,
Klaus
