[Evolution] New IMAP messages slow to appear in message list

[Matt Nelson <mnelson dynatec com>]

I am connecting to a Exchange server via IMAP with Evo 1.4.4.  I 
frequently notice that  Evo will indicate that there are new messages in 
my INBOX - both in the folder pane and in the INBOX folder title bar - 
but not update the actual subject listing in the subject pane.  In other 
words, I might be told that there are 10 new messages, but I cant see 
any of them in the message pane.  I have tried clicking send/receive, 
ctrl-e, move back and forth between the INBOX and other folders - 
everything I can think of.  The only thing that seems to work is just 
wait until Evo decides to update the message list, which can take 
several minutes.  Annoying to say the least, completely unacceptable to 
say the most.

Has anybody else seen this?  Is there a workaround?

I find it frustrating that IMAP continues to seem so unreliable in Evo. 
  Although I really like it in all other respects, I think I might be 
forced to go back to Mozilla mail...
