"Post Your Listing at $" button not displaying properly on phones

I just purchased the latest version of the theme (1.8.6) today. When I loaded on two of my smartphones, a Motorola Droid RAZR and a Samsung Galaxy S3, using the latest version of Chrome as the browser, the orange "Post Your Listing at $" button did not display properly.

It looks like the two end caps are on one line, the rectangle containing some of the text is on the next line and the "$26.00" shows up on a third line with no orange background. Here's a photo showing the issue:



Can you tell me where to modify the code and what to change to fix the problem or will you post and update soon?

Thanks,
Greg A.

 

I went into header.php and shortened the text and that fixed the problem for now.
