I see what you are talking about.
I'll let the folks know about this.
Thank you James!
I know y you do forums, but maybe you could tip off the news section there's a problem with their webpages. It's the popout column from the left side with list of stories. There's a scroller there between it and the content area, but for me on FF28 it won't work to scroll the left column, but using the mouse wheel at least does. It's not just one page, but here's one you can try it on. For it to appear you have to move the page down a bit and then the left side offers the pop out.
This not only happens in Linux using FF, but in Windows 10 using Edge.
In addition, getting it to move results in the content page moving left to right or up and down. It's action is very odd. Only the wheel works for scrolling the left column list of stories.
I tried it also in IE 11 in W10, but never saw the left read border indicating the pop out appear.
