A fix will be available in the next update.
Until then, you can attach the following as a .js file in the Resources section of the in5 export dialog:
$(window).load(function(){
var $slider = $('#slider');
var slider = $slider.data('AnythingSlider');
nav.to = function(n,c){
if(c){
var offset = $slider.offset(), cScale = getCurrentScale($('#container'));
slider.scrollAdjust = (pageMode=='h' || pageMode=='fade') ? function(){ $(document).scrollTop(offset.top+c[1]*cScale);} : function(){$(document).scrollLeft(offset.left+c[0]*cScale);};
} else slider.scrollAdjust = undefined;
if(n == slider.currentPage && slider.scrollAdjust){
slider.scrollAdjust();
delete slider.scrollAdjust;
} else slider.gotoPage(n);
};
});
