Please don't top-post, thanks.

Maybe it's an IE bug, or maybe IE is doing something funny depending
on it being in compatibility mode or the likes. Maybe it wants a
specific syntax to refresh the frame instead of the whole window.

SquirrelMail is using a meta tag refresh and while it would be nicest
if you could help diagnose what is happening, you could also use one
of the new refresh mechanisms added a couple weeks ago to 1.4.23-SVN
(snapshots on our downloads page).

Another thing you can try very easily is changing the browser
rendering mode setting in the SquirrelMail configuration.

You can also test by creating a simple frameset where one frame has a
META refresh in it.  I'm leaving DOCTYPE out, but that could also have
an effect:

<html><head></head>
<frameset cols="200, *">
<frame src="left.html" name="left" frameborder="1">
<frame src="right.html" name="right" frameborder="1">
</frameset>
</html>

right.html

<html><head></head>
<body>Hello World Right
</body></html>

left.html

<html><head>
<meta http-equiv="REFRESH" content="5;URL=left.html">
</head>
<body>Hello World Left
</body></html>

Along with various DOCTYPEs, you can play with the syntax of the meta tag:

<meta http-equiv="REFRESH" content="5">
<meta http-equiv="refresh" content="5;URL=left.html">
<meta http-equiv="refresh" content="5">
