You'll find a hard time finding anyone around here with a Mac to help with this. Your page ran fine in IE5 PC here but, had problems in Opera8.51. I'm hoping the solution there will help with the solution for IE5.2 Mac. Here's the trouble with Opera, this tag (from your version) has lots of extra stuff that could confuse almost any browser:
HTML Code:
<div id="motiongallery" style= "color: black; font-size: medium; font-family: serif; text-align: left; visibility: visible; white-space: nowrap; display: block; position: absolute; top: 0; right: 12px; bottom: 12px; left: 0; width: 1px; height: 12px">
I'd try using the default settings for this tag, especially as what you have makes no difference between that and itself in a browser where it does work. In other words, substitute this for the above:
HTML Code:
<div id="motiongallery" style="position:absolute;left:0;top:0;white-space: nowrap;">
