Theme broken on IE6

It also shows up in FF1.5. When I'm logged as admin - everthing is ok, when I'm logged as normal user (authenticated) then it corrupt.

drupal 4.7 here: In FF 1.5 it looks fine but I also get the problem in IE, the contents of the right nav bar end up on the other side of the page.

I got it working in FF and IE by changing this definitions of .primary and div.secondary. Here is the revised code:

.primary {
	width: 500px;
	_width: 500px; 
	float: left;
	padding: 20px 0 10px 0px;
	margin: 0 0 0 30px;
	_margin: 0 0 0 15px; 
	}

div.secondary {
	font: 1em/1.5em 'Lucida Grande', Verdana, Arial, Sans-Serif;
	padding: 10px 0;
	margin: 0 0 20px 76%;
	_margin: 10px -10% 10px 80%;
	width: 20%;
	_width: 28%;
	color: #666;
	position: relative;
	}

Hope that helps someone! Still a lot of other bugs in this theme for IE6...

Sorry, here again revised with a little more finesse:

.primary {
  width: 500px;
  _width: 500px; 
  float: left;
  padding: 20px 0 10px 0px;
  margin: 0 0 0 30px;
  _margin: 0 0 0 15px; 
  }

div.secondary {
  font: 1em/1.5em 'Lucida Grande', Verdana, Arial, Sans-Serif;
  padding: 10px 0;
  margin: 0 0 20px 76%;
  _margin: 15px -10% -10px 78%;
  width: 20%;
  _width: 28%;
  color: #666;
  position: relative;
  }

And add this:

.block {
  _margin-bottom: 20px;
  }

Well, I tried to apply the fixes suggested by JamieR, but my right column still is displaying at the bottom of the page with Internet Explorer. Any progress on this?. Thank you
