Hi

It's because the article height triggers the sticky menu but it's on the border line so it bounces as it doesn't have height on screen to display it properly.

It's a limitation with the concept of sticky menus - I don't see it because my screen is taller so the sticky menu isn't triggered - like wise people with a shorter screen would see it working normally

Fixing it is a problem as its a limitation of all sticky type menus - is it possible to add more content e.g module?

Cheers
Paul
