Yep, this happens because something is trying to update your vm INBOX while
your reading it. This is a bad thing (TM). 

Are you using procmail or some other program to sort/process your mail and
then write it directly to the INBOX folder? If so, don't. 

Basically, you need to write to a *.spool file. then when you visit the
mailbox, it reads mail from the *.spool file and puts it in the main
file. If, while reading the mailbox, you hit g, it will check the spool
file and read in the mail.

You shouldn't need this with the INBOX file. This is handled by the
movemail program and reads mail from the system mail folder
(i.e. /var/mail/username) into a file called NEWMAIL. When you start vm, it
looks in NEWMAIL and reads that mail into INBOX. The contents of INBOX
should only be modified by VM (usually, by hitting 'g'). 

Note that as vm is extremely configurable, names like INBOX, NEWMAIL,
*.spool etc, are all controlled by variables and could be different,
depending on what has been customized etc.

Check the vm website and documentation for more information - in
particular, the FAQ has a section about using procmail, which should
explain everything.
