Modal window causes page to scroll

Hey guys,

I am trying to use a login plugin that opens a modal window when clicked. It works fine on other themes, but on enfold it causes the page to scroll. I noticed that in enfold it adds #login-box to the url and it doesn’t do that in other themes. visit http://onecraftyshop.com to see it in action. Click login in the nav menu. It should scroll down a little. Scroll the page down a little and do it again to see it still scroll down. That’s how I know it isn’t the #login-box div that is causing it to go to a specific part of the page.

Thanks
