Move to top arrow

Hi,
I am using the hot destinations template on two of my sites but everytime I install it, after using it for two days or so, when I click on the "move to top" arrow, it just disappears and nothing happens. Is there any way I can make it work or maybe just remove it completely.

Thanks

add this css to template_css.css:

#top-link{
display:none;
}

that will make is desapear.
