Interesting.  Can you tell me the semantics of the caching offhand, or point
me to where in the code I might look?  I wonder if this is something that
manifests itself more on smaller systems; in my case, I'm the only user.  If
I mark a message as seen using OE6, then refresh, the message becomes
unseen, every time.  Only switching folders (which probably closes the IMAP
connection) makes things stay seen.

It sounded from the earlier discussion like the caching wouldn't be affected
by multiple users, only by how quickly the client closes the connection, but
if nobody else is running into this, maybe it is affected by simultaneous
users as well?
