Home Link Behavior

Site:

http://www.sneakyclub.com

as of now, it works like i want it…

if you hit home it goes back to my splash page, which is how I want it.

There are some generated links for Admin control panel, like in the media category, that uses the ?attachment_id (an example) tag.

it automatically redirects to the splash page.

How do I change so that 1) either those dynamic links are not used or that it adds the prefix to ? of index.php

THanks a bunch
