[syrus.xl]

If you're using a non-standard style then it can be adjusted accordingly. It will even work with image buttons if coded correctly.

In your circumstances you just need to remove the default TD tag, so your code looks like this:

<!-- Mp3 Player Launch -->
<if condition="$show['member']">
<a href="javascript:NewWindow=window.open('mp3playerindex.php?do=viewmp3playerpopup ','newWin','width=500,height=500,left=0,top=0, toolbar=No,location=No,scrollbars=1,status=No,resizable=No,fullscreen=No');
NewWindow.focus(); void(0);">vbMp3 Player</a>
</if>
<!-- End Mp3 Player Launch -->

Hope that helps!
