[Evolution] How to make Folders and vFolders re-count emails ??

[William Case <billlinux rogers com>]

Hi;

It's a long story that is about a fresh Fedora 10 install -- don't ask.

But, my folders and vfolders are now showing a miscount of the number of
read and unread emails in each.  Sometimes they give me a negative
count.  

Is there anyway to make Evolution recount each folder and start again
with real numbers?
