MCs won't stop loading

Ok, this may be a little challenging for me to explain. In my portfolio section, I have a few links under an empty movie clip. These links are client names. When clicked, they are supposed to load an external swf into the empty movie clip. The problem is that if I click on one, then rapidly change my mind and click on another, the originally clicked external swf never stops loading and then my links stop responding. I appreciate any help. Thank you! Aubrey
