Please see this example:

If you click 'Live Demo' at the top of the page and then click on one of the large buttons, such as 'CHECK OUT THE CALENDAR SECTION', then most of the time it works. But if you select the very top 1px of the button (the pointer does change to the hand) then it won't fire. You can literally keep clicking the top 1px and nothing ever happens.

It may not seem much of a problem, but I am using this theme on a site and it's surprising how often when testing that I click the very top of the button resulting in no action, only realising a couple of seconds later when the page hasn't loaded. It's very annoying.

How would I change this, I'm guessing it's CSS?

Tested on Safari and Chrome.

Thanks for any help.
