Javascript problem on Macs

[kish]

Hi all,

hoping for some help on those of you that use macs or know the answer to this problem!

I have a page that works perfectly on IE6, Netscape and Opera on the PC.
However its not working properly on IE5 on Mac OS x.

Basically I'm using javascript to create two scrolling columns on the page. The columns should scroll up and down when you hover over the little arrows underneath the columns. On the mac its not scrolling and the content in the right column seems messed up.

You can view the page at: http://test.jdartstudios.com
You can view source to check out the JS.

I have also attached an image showing how it renders on IE6 on the pc so you know how it should look.

Any help/advice would be appreciated!

Thank you !
