This is caused from the index.htm page, where the frame sources are referred to as "about:blank"."This page contains both secure and nonsecure items. Do you want to want to display the nonsecure items?"
Since the redisplay function takes care of the frame sources, the "hard coded" sources could refer to any nonsens to avoid this user critical message.<html>
<head>
<title>InfoCenter Manual</title>
<script language="JavaScript" src="$infocenter_content.js"></script>
</head>
<frameset cols="200,*"
frameborder="0"
framespacing="1"
border="0"
onload="$reDisplay('',1,0,0);">
<frame name="$hmtoc"

<frame name="$hmcontent"
src="about:blank">
<noframes>
This page requires frames<br><a href="infocenter_content.htm">Click here to view the table of contents without frames</a>
</noframes>
</frameset>
</html>
P.S the "$" prefix causes lots of grieve with browsers, ftp uploads to regular hosters.<html>
