With Gary's help, I created a pop up menu - https://www.talkgraphics.com/showthr...own-menu-width - for the mobile version of a client's site.
It works perfectly as long as the vertical window scroll bar in any browser is at the top of the page - but as soon as you have to scroll down the page, the menu stops working - the pop up shows and the relevant page gets highlighted - but it simply wont go to that page.
If you scroll to the top of the page - the menu works again.
Any ideas gentlemen?
