Hi Folks:

Okay, here's what I'm talking about...  A sample system.  Four files.

index.php     main page holding the frameset.  frameset has two
              frames.  one on left.  one on right.
left.php      navigation menu that goes in the left hand frame
right.php     content in right hand frame.  this page is the default
              one that comes up in the initial frameset.
right2.php    another page for the right hand frame


***************** index.php ******************

<?php
#   This has no effect.
#   header('Window-target: _top');
?>

<html>
<head><title>index page</title></head>
<frameset COLS="120,*">
<FRAME SRC="left.php" name="menu" scrolling="no">
<frame src="right.php" name="content">
</frameset>
</html>


***************** left.php ******************

<?php
#   Turning this on will jump this page out of the frames.
#   header('Window-target: _top');
?>

<html><head><title>the menu</title></head><body>
<a href="right.php" target="content">right</a>
<br /><a href="right2.php" target="content">right 2</a>
</body></html>


***************** right.php ******************

<?php
#   Turning this on will jump this page out of the frames.
#   header('Window-target: _top');
?>

<HTML><HEAD><TITLE>Right</TITLE></HEAD><BODY>
Hi there. This is the main content page in the right frame.
</BODY></HTML>


***************** right2.php ******************

<?php
#  This has no effect.
#  header('Window-target: _top');
?>

<HTML><HEAD><TITLE>Right 2</TITLE></HEAD><BODY>
Hi there. This is the secondary content page in the right frame.
</BODY></HTML>



Now, put all those files on your machine.  Hit index.php and you'll see 
everything normally.  Then, uncomment the header function in left.php or 
right.php and you'll see that page jump out of the frames.  But, turn 
the header on in index.php or index2.php and you'll still be in the 
frames.

Enjoy,
