Cursor fails to indicate presence of Hyperlink

When I bring the cursor over an image that I use as a Button, the cursor
fails to give an indication (arrow to finger) that there is a hyperlink for
the button. I am using Word 2003. I can modify the HTML in NOTEPAD to make
it work but I can't seem to be able modify it or get it to work properly
using Word's Script Editor. It works fine if I use a piece of text as a
Button.

Any thoughts or ideas would be appreciated.

Thanks
