Vista - WLMD MS discussions bug

When I post a new news message on the MS discussion groups with WLMD and
view the discussions groups through the browser version, my post date is
27/06/2006 (which is wrong) with the tree "collapsed" and the "right date"
with the tree "expanded" (when I view these groups in WLMD all dates are
right).

e.g. my posts in this group concerning WLMD on 24/06/2006 and 25/06/2006

This is getting relly weird. My recent posts have 28/06/2006 as "collapsed"
post date (25/06/2006 expanded), while my last post has 25/06/2006
(collapsed and expanded, as they all should have been). Without changing any
config...
