Bypass
I played with your scrollbar, and the only thing I had was that positioning the scrollbar is weird, it seems to depend on the scroll of your jspPane . I canβt understand why.
In any case, if you can control the way jsscrollpane initializes the panel, it seems that if you move jspHorizontalBar to make it a direct child of tiascrollpanehor as follows:
<div id="tiascrollpanehor" class="scroll-pane jspScrollable" style="overflow: hidden; padding: 0px; width: 525px; " tabindex="0"> <div class="jspHorizontalBar"> <div class="jspContainer" style="width: 525px; height: 439px; "> ....
It positions itself well , but is not user-driven. To fix this, add
.jspHorizontalBar{ ... z-index:2; }
I still canβt explain why this is so, but I hope this fixes this error for you (since I cannot change the structure of CSS and HTML before the page displays).
