Notes/Domino 6 and 7 Forum : Frameset and Netscape7

I have a 4-frame framset. When looking at the application from an Netscape 7 browser the top frame is not loaded (most of the time, but somtimes it does). I have tried to make the url computed and not computed, relative and not relative, and no difference, whatsoever. The other frames are computed in the same way and they load correctly.

Has anyone experienced a similar problem, and have a clue to why this happens and if there is a workaround.

The html produced by domino looks like:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN">
<html>
<head>
<title>Application - Blekinge Institute of Technology</title>
<script language="JavaScript" type="text/javascript">

</script>
</head>
<frameset frameborder="0" border="0" rows="80,1*,20">

<frameset frameborder="0" cols="200,1*">
