This has come up a few times recently.  And nobody has shown that it  
is a Horde issue yet.  It sounds instead like a c-client issue.  As  
Joe suggested, try changing the sort order in the mailbox.  Issues  
with a certain sort style in a mailbox would explain why messages are  
viewable in a virtual inbox vs. the regular inbox.
