Question

How can i make the user aware of a button (OnClick Event) when there is now link (HREF) attached ?

Answer

Use a CSS style with a OnMouseOver event.

Create the following style in your document or CSS:

<style type="text/css">
<!--
.cursor {  cursor: hand}
-->
</style>

Attach it to the OnClick Event:

OnMouseOver="this.className='cursor';"
