Sunnysw on "[Theme: Intergalactic] Hmm, the menu goes invisible when scrolling down"

Hey guys!

First off, this theme is gorgeous. Superb work, I cannot say otherwise.

I just have one conce right now, though, which is that: When I scroll down, the menu toggle seems to disappear.

This is my site: http://www.genecarlyle.com

Is it possible to, when scrolling down, still be able to see and click that square up in the top right coer? That is, so its position is fixed?

Thank you guys a ton.
