[jQuery] keep user from clicking links while cycle is in motion

I am working on a site here: <a href="http://adc4web.adceval.com">adc4web.adceval.com</a> I have a problem where while the cycle is shifting a page, the user can still click a link and this screws up the cycle after clicking a bunch of links. Is there a way to prevent the user from clicking a link until the cycle is done?<div>
Thanks</div><div>Mike</div>
