Redifing width in enscroll has problems

[ghost]

I have a responsive web page that will scroll with Enscroll. My problem is when I resize the page, the scrolling div will resize and that is what I want. But when I resize the page again to get bigger, The scrolling div won't get bigger and Its size is at the smaller size that I have resized the browser.

What should I do for that? I tried this code but It had problem. Because when I resize the page, scroll track and handle will repeat in the page:

$(window).resize(function(){
$(".mydiv").enscroll();
});

[s-a-s-k-i-a]

This is also true for simply switching forth and back between portait and landscape mode on mobile devices.
This is an annoying issue.
Please provide a fix.

Thanks!
