Margin is too large in IE6

I've got a simple test page that contains 4 divs.  The first 3 are floated left and have margin-left of 50px, and the last one clears the float and also has a margin-left of 50px.  What I expect is for the first and last divs to line up, since they both have the same margin on the left side.  Mozilla seems to do this, IE6 does not.  I've got a strict doc type, so I assume it's not a quirksmode issue.  I assumed it was an IE bug having to do with float touching the clearing element, but even if I set a margin-top on .clear, the divs didn't line up.  What am I missing?

<head>
<style type="text/css">
.myFloat {
  float: left;
  margin-left: 50px;
  width: 150px;
  height: 175px;
  border: 1px solid black;
}

.clear {
  clear: both;
  width: 600px;
  margin-left: 50px;
  margin-right: 50px;
}
</style>
</head>

<body>
<div class="myFloat">TEST</div>
<div class="myFloat">TEST</div>
<div class="myFloat">TEST</div>

<div class="clear">CLEAR</div>
</body>

It's an IE bug but there's a workaround ;)

Just add a "display: inline;" to your myFloat class declaration, like this:

.myFloat {
  display: inline; /* prevent IE doubled float-margin bug */
  float: left;
  margin-left: 50px;
  width: 150px;
  height: 175px;
  border: 1px solid black;
}

The bug in IE is that it does the clear wrong.  To line them up just float the "clear" div:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

<html>
<head>
<style type="text/css">
.myFloat {
  float: left;
  margin-left: 50px;
  width: 150px;
  height: 175px;
  border: 1px solid black;
}

.clear {
  float: left;
  width: 600px;
  margin-left: 50px;
  margin-right: 50px;
}
</style>
</head>

<body>
<div class="myFloat">TEST</div>
<div class="myFloat">TEST</div>
<div class="myFloat">TEST</div>

<div class="clear">CLEAR</div>
</body>
</html>

Yup, that did the trick.  Funny, I was looking through Holly & John's site before I posted, but I didn't see that section.  Thanks though, that makes one more random IE bug I know how to kill.  Cheers.

changing the display to inline is not necessary and my cause other rendering problems if you have to put other elements inside the final div.

Oops, sorry Cd&, I didn't notice your post there.  According to the CSS2 spec (and the link that Kupi posted), when an element is positioned with float: left:

The element generates a block box that is floated to the left. Content flows on the right side of the box, starting at the top (subject to the 'clear' property). The 'display' is ignored, unless it has the value 'none'.

The last line, in this case, indicates that there won't be any rendering problems, but for some odd reason, it means that IE behaves properly.

I did try your suggestion, but it creates a horizontal scrollbar in IE, which wasn't the original intention.  Thanks for the input, though.
