Outlook won't break lines in received plain text e-mail

[FA]

Hello.
I'm using Outlook 2000 on Windows XP. I moved my .pst
file from another Outlook 2000 on Win98.
Plain text e-mails show no line breaks. I remember on the
previous Outlook I modified a registry key so they would
show correctly.
Do you know how to fix this?
