HTML expert advice needed

It appears that IE7 deals with target frames for links differently to IE6.

<frameset ROWS="80,*"frameborder="0" framespacing="0" border="0">
<frame name="head" scrolling="no" target="main" src="head.htm">
<FRAMESET cols="125,*" frameborder="0" framespacing="0" border="0">
<frame name="left" scrolling="no" target="main" src="left.htm">
<FRAME src="home.htm" name="main">

Links in frame head & left should open in the target frame main

This works in IE6, but not IE7.

My head now completely mashed

Help.
