When we last heard from you, the following words rang out across the 'Net:

The Javascript alert works in IE5.  I don't think the "first message in your
mailbox part" does though.

I had cobbled together a very basic HTML message consisting of:

<HTML><BODY>

-YOUR FAVOURITE CODE HERE INCLUDING ASCII replacement for javascript-

</BODY></HTML>

I can't see that Hotmail will ever be able to block javascript if this is the
case...think..you could replace any letter, or any combination of letters.
Major coding hassle.
