Responsive design hides menu structure

Hi folks,

first of all – very great work! After that honey i must report a “bug”, i guess only a small CSS fault.

I use your current theme version 1.0.2.1 with current WP version. I use the color schema “white” und i have also created a menu in WP. In the webbrowser the site is working fine, but at my Smartphone no menu is shown. I checked it also at my desktop computer and resized my browser windows to a small witdh. And what happens, the menu is shown but also in white color -> color of menu changes from black (standard at this color schema) to white and you are not able to see the menu ??

I hope you can fix this small bug very soon, so i can use this great theme also on mobile devices.

thanks and greets, Fl0W
