OWA Red X's when sending/replying to e-mails

[Jeremy]

I just rebuilt my wifes computer and installed Windows XP
Pro, Office XP Pro, and all of the windows updates
available. She is able to log onto her Outlook Web
Access and view e-mails. Unfortunately, when she tries
to reply or create a new e-mail the message field has a
red X in the upper left corner. Any ideas on how to fix
it?

I'm having a similar problem sending/replying to an email in OWA using
Windows XP Pro

I can read email, but cannot reply, send or forward. No error
message. You click on
send and nothing happens. You eventually have to just close the email
-
which then sits in your drafts box. Once you connect using Outlook
everything is fine. I have several users who have Windows XP Pro who
have
this problem.

Any help will be greatly appreciated.
