Found the problem - it has to do with how my "<body onload" coding was done.
The correct code order is:
Code:
<body onload="P7_initPM(1,0,1,0,0);MM_preloadImages('../../template-files/2newsletter.jpg','../../template-files/2festool.jpg','../../template-files/2internetstore.jpg','../../template-files/2flitch.jpg','../../template-files/2cart_empty.gif')"{$reading_direction_tag}{if $body_onload ne ''} {$body_onload} {/if}>
