User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10

The comments are in: <html><body><div><div style="float:right"><div>
and it's the first tag in that 3rd div

This comment displays starting with "-- BEGIN"
<!-- BEGIN -- This is an HTML comment and should not show -->

This comment doesn't display at all (correct)
<!-- BEGIN This is an HTML comment and should not show -->

On further investigation... adding a <!-- END -- text here --> makes NOTHING
display between the comments.

Reproducible: Always
Steps to Reproduce:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Page Title</title>
</head>
<body>
<div class="header">
	<a href="www.mozilla.org"><img src="images/logo.gif" alt="" width="55"
height="55" /></a>
	<h1>Site title</h1>
</div>
<div class="clearing">&nbsp;</div>
<div id="wrapper">
	<div class="container">
		<div id="main"><p></p>
			<!-- BEGIN -- This is a comment and shouldn't display -->
			<div class="class1"><img src="images/image1.gif" /></div>
			<h1 id="topic">Main Title</h1>
			<h2>Title</h2>
			<p>
			Paragraph 1
			</p>
			<p>
			paragraph 2
			</p>
			<!-- END -- This is a comment and shouldn't display -->
		</div>
	</div>
	<div id="nav">
		<ul>
		<li></li>
		</ul>
	</div>
<div class="clearing">&nbsp;</div>
</div>
<div id="footer">Copyright &copy; by me</div>
</body>
</html>

Actual Results:  
incorrect browser rendering.  try adjusting the -- after BEGIN or END and see
the results.  I'm using Firefox PR1.0 (and just downloaded a critical update)

Expected Results:  
check IE... I hate to say it, but IE displays this (one and only) thing correctly.

it appears to have something to do with me putting BEGIN and END in my comments.
 i was blocking out an editable region for my own purposes when I noticed this.
 Hope this is news to you, and not a waste of your time.  thanks
Your comments are invalidly formed, which is why the display is breaking.  You
cannot put -- in the body of a comment, because that closes the comment.
