TD background problem in Safari

[Anders Studio]

Hi.
I have a TD attribute set to a background image that varies in length depending on how much text is entered down the right column (see link below)

This works just fine on PC in IE, Mozilla, and Netscape, but the background image fails to display in Safari on MAC.

How can I make this work in Safari?

Here is the link:
