Cannot write emails with OWA 2003 + Vista Pro x64

Hello fellows,

I’m testing Vista Professionnal 64bit.

My company uses Outlook Web Access 2003. I can read the emails, public folders… but when I want to write an email or reply, the editor section where to write the email looks like an unloaded picture and I cannot enter any text.

Does one of you know a fix for this issue?

Thanks in advance
