This problem happens 90% of the time with chrome/ie11 and occasionally with firefox. If you are viewing the very top of the page it always works.
If you make one of the links in a menu to an id (#s5_top_row2_area1 for example in the BigPicture theme) it puts an onclick="s5_page_scroll(#s5_top_row2_area1 )" on the <a> and turns the puts href="#". Whenever you click on this link from a different location on the same page you get a quick flash of the loading location and then the page scrolls as normal. If I remove the href="#" the scroll works as normal.
Do I need js that goes overthe menu and removes href='#' ? If anybody else has had this problem and knows an easy fix please let me know!
