no border around hyperlinks with hyperref
This is not a problem with TeX. Displaying the box is up to the PDF viewer. So, the above code (run on Mac OS 10.9.5) with TeXShop 3.45.1 is shown as follows:
TeXShop 3.45.1 Viewer: no box
Acrobat 11.0.9 : box
Mac Preview (Mac OS 10.9.5): no box
Firefox 33.0.2 (Mac OS 10.9.5): box
Chrome and Safari (Mac OS 10.9.5): no box
To simply resolve this problem put this in your document after the "\usepackage"es
\hypersetup{pdfborder = {0 0 0}}
