After playing around a little more, I found there were further problems in using the onblur to keep the focus, such as not being able to get to the address bar. The following addresses that problem & I've added an onfocus event to stop the document body getting focus (the grey border effect). Hope this works for you.
frame2.html
<html>
<frameset cols="20%,20%,*">
<frame src="frame2b.html" name="FRM2B" onfocus="document.all.FRM2A.contentWindow.focus()">
<frame src="frame2c.html" name="FRM2C" onfocus="document.all.FRM2A.contentWindow.focus()">
<frame src="frame2a.html" name="FRM2A" onload="this.contentWindow.focus()">
</frameset>
</html>
frame2a.html
<html>
<body onfocus="document.all.GF.focus()">
Frame 2A<br>
<form>
<input name="GF" type="text" width=120><br>
<input type="text" width=120><br>
