Wierd browser issue with ASPX

[VB Programmer]

I have a ASPX login page that works fine on most pcs. One of my clients has
trouble with this page. He's tried both IE and Crazy Browser (based on IE)
and whenever he hit's "submit" it refreshes the page and doesn't log him in.
It works fine in Firefox.

Any ideas?

For starters, I would make sure that the client is communicating with the
server. If this is a production page, then make a copy to something
non-guessable like "login_2394343.aspx" and on postback do something simple
like redirect to yahoo. If that works, then you know the answer is in your
code (probably validation works differently for that client - or he doesn't
have javascript, etc.) and not the browser's fault.
