First of all great theme I have been using it successfully for a year now on a site with many thousand visitors a month.
I have just updated classipress to the latest version with responsive layout and updated Headline child them accordingly. The issue I have is that when viewing on a mobile device both the regular menu and the responsive drop down menu appear (see screen shot) and the "Post An Add" button disappears.
Also another minor issue I have found is that the adds in the add listing pages (and home page) do not have the padding on the right hand side.... I also see this on the demo of the Headline theme as in screen shot attached.
Any help you can give would be appreciated.
