Internet Explorer忽略Javascript

Question

I've recently been trying to include a Lightbox-Clone called "EnlargeIt" into my website. Everything works fine in every Browser except, big surprise, Intenret Explorer. Let me quote directly from the manual:

Integrate your thumbnails like this into the of your web page:

<a href=”images/fullsize_file.jpg” target=”_blank” onclick=”return false;”><img 
src="images/thumb_file.jpg" alt="My first picture" onclick="enlarge(this);" 
longdesc="images/fullsize_file.jpg" /></a> 

The attribute longdescis used for the qualified filename of the full size image, meaning that if the file is in a different folder, the correct pathmust be included (in the example, it's images/). The attribute altis used for the picture caption. If you don't define it or leave it empty, no caption (title bar text) will be displayed for thispicture. Around the image, there's an …element linking to the full size image in a new window (target=”_blank”). It's very important, that you set the attribute onclick=”return false;”. This way, the link won't be used if Javascript is available.

I've done exactly as said in this manual and it works fine until you try it with IE9. You click on it and it does...nothing at all. Every other Browser handles it correctly, even older versions of IE. It does show the link while hovering over it but I guess the "return false" prevents the default action?

My Code:

<a href="fileadmin/templates/HTML/main.html" target="_blank" onclick="return false;"/><img src="fileadmin/templates/images/logo_subline_moreInformation.jpg" style="width: 520px; height: 130px; cursor:pointer;border:none;border-width:0px;text-decoration:none;" alt="Alt" id="Image"
  onclick="enlarge(this);" longdesc="ifr::fileadmin/templates/HTML/main.html::800::600"/></a><br>

Thank you!

Oh and have a nice day!

With a little googling... Doctype issue? http://enlargeit.timos-welt.de/forum/viewtopic.php?p=471&sid=4540aa596fcc5870fe02618e27d374dc
