Different Safari Behavior on Different Computers--Help

Hi,

I have late 2013 MBP and early 2014 MBA. Both are operating under 10.10.2 and Safari 8.0.3

I have website that I am setting up with Superlative for my real estate business. At the bottom of the home page there is a Site Map. The Site Map is a pull down menu with a series of links to various webpages.

On my MBA clicking on one of the links will result in going to the webpage associated with the link. All works fine. However, on my rMBP the links do not function.

I have reviewed the Safari preferences on both the rMBP and MBA and both are set up identically.

Any thoughts as to why I get different behavior for Safari on rMBP and the MBA.

Cheers,

Don Barar
