Clicking any hash/"#" link, even in Seven themed edit page tabs, scrolls to top of page?
Your problem appears to be that the arrows for the slide show and "logo parade" are linked directly to their container &lt;div id="logo-parade"&gt; with the anchor href="#logo-parade", which causes the page to essentially "snap" to the container, since the div id is the same as anchor when called as a hash (you can see in the url that #logo-parade gets appended).

This could be caused because of a portion of javascript is not being called/run properly which should trigger the carousel without needing to use anchors.

Since your problem doesn't occur in development (you can test this by clicking on one of the arrows and making sure that in your URL bar you don't see #logo-parade appended) it leads me to believe that perhaps a file hasn't loaded correctly on the server, or perhaps the .htaccess rewrite has something to do with it
