I too was having the same problem (import the mail, everything is fine, close
Win Mail, bring Win Mail back up, and no messages).
Yesterday afternoon, I imported the messages again, and everything seemed to
be okay.
This morning, I fire up the comp, go into Win Mail, and no messages. Won't
even check for new e-mail messages.
I have been working on this problem for 4 days now. And throughout this
whole time, I suspected McAfee as being the problem, as I kept seeing the
McAfee scan box come up, each time I'd enter Win Mail.

So, without doing another thing, I closed Win Mail, un-installed McAfee, did
a restart, and when the comp came back up, I opened Win Mail.

Low and behold, everything was there!
Win Mail checked for, and downloaded new messages without a hitch.

Not only did un-installing McAfee resolve my Win Mail problem, I also no
longer have to deal with those annoying, whiny little McAfee pop-ups about
registering the software, every 5 minutes.

I'll be installing Zone Alarm, once the Vista version is available.
