I am sending an HTML email newsletter and although all my buttons work in the preview (all linked to pdf documents, stored online) when i try them from my hotmail account (froma test of the newsletter i have sent to myself) they don't work? Does anyone know why?<br /><br /><!--c1--><div class='codetop'>CODE</div><div class='codemain'><!--ec1--><br /><br /><button onClick="window.open('http://www.the-insurance-surgery.co.uk/fs_adv.pdf')">ADVANTAGES OF THE FULL SERVICE</button><br /><br /><!--c2--></div><!--ec2-->
