Site homepage not clickable in Chrome and Firefox on first load

Hi,
YNFA.NET Homepage is Unresponsive in IE and Firefox on the first time of loading. Due to this new users can’t login or try to register. If they click on another page and then go back to the homepage to either register or login they can then do it. Its almost like the homepage unlocks when you navigate away and then back to it.

Pls help!!
