I noticed that Message-ID: <cthahu$7gm$1@sparta.btinternet.com> from

Actually it's not bad enough to cause the error but I think it could
lead you into bad habits. I find it easier to be consistent in my use
of superglobals and use them like so :- $_POST['user']

If you tried to do
echo $_POST[user];
You would get a warning notice. It only works in your case because it
is contained within double quotes. I find it simpler to use just one
way. Unfortunately this means you have to write the lines as:-

echo "<p>Welcome <b>".$_POST['user']."</b>!</p>";
echo "<p>Your message is:<br><b>".$_POST['message']."</b></p>";
But it saves you having to think of whether to use single quotes or not.

Also, it's a good idea to check if variables exist before using them. I
know this script won't get called unless the POST variables exist, but
again it's all about good habits.

As for your original problem. Sorry, can't recreate it - it works fine
in IE here.
