Internet Explorer 7 and previous versions have a strange behavior dealing with links containing "javascript:" hrefs.

In fact if an HTML "A" element similar to the one below is used in a push-page to run javascript code, then the streaming gets stopped:
Code html:
  1. <a href="javascript:myStuff()">Click</a>

You can use a link like this one to avoid the problem:
Code html:
  1. <a href="#" onclick="myStuff()">Click</a>

The issue is solved with IE8
