You will see I have two Parent enclosing DIVS named/class of sectionwrap each with a unique ID, within each of these Divs there are two child divs.
The problem I have is that the menu marker is out of sync because the enclosing parent DIVS only cover the first of the two child divs, so as the page is scrolled down the marker disappears and then reappears early for the second Parent DIV.
It all has to do with the 100% page height - but I cannot work out the solution.
Any help would be appreciated
