Delay during loading on a show/hide script.

Delay during loading on a show/hide script.

I recently set up a JQuery script to show and hide a specific DIV on my site. Everything is working correctly except when the page is loading, the DIV is fully expanded and hides as it's supposed to a few seconds later. Ideally, I would like this DIV to remain hidden until the user actually clicks on it. This seems to be a performance issue, but honestly I am a JavaScript novice so I really don't know where to go from here.

The page in questions is here. And the specific areas that use this script are the "Change Log" and "Readme" boxes.

Any help would be greatly appriciated
