Bug when open on a mobile phone

Hi

Great design!

However I’ve found that if I open a site with your theme on a mobile phone (I tried samsung s3 and note1), then the menu doesn’t work correctly. Firstly it is shown ok, when you press on the menu icon, but if you scroll posts up (and they “move” the menu up ), they “in reality overlap” the menu. So that if you touch the screen with a post in the area where menu items were, you are pressing the menu item and get redirect according to the menu configuration.

Thank you and best regards
Sergey
