Firefox OK, Older Safari (5) won't close using the close class

[gabrielhart]

Just checking my code but all looks well and it works on FF. My Safari browser does everything right but when I click the close nothing happens and no clicks are processed.

EDIT: The provided minified zip on google did not work for me. Re-minifed from original and all good. Still remains the issue with Safari not responding to the close using anchor tag and simplemodal-close class.

Any thoughts?
