Simple button not working, unless I hit F5

Simple button not working, unless I hit F5

I have a strange bug   http://goo.gl/GhVzL  When I click on 'Planificador de viaje', I get taken to this page http://goo.gl/CZaaQ 

This is as expected, but when I click on 'OK, entiendo', the button doesn't work UNLESS I refresh the page.  Any clues?  There are no alerts in my Javascript console in Chrome.

However, when I look at the Error Console in Firefox, I see that this warning initially appears "Error in parsing value for 'pointer-events'", but then vanishes when I hit F5.  I've searched, but cannot locate what the error message means.

I borrowed the original code from here:

Desparately trying to get this resolved for tomorrow :)
