[Evolution-hackers] Message remove how-to?

[Smartuser <smartuser gmail com>]

Hello,

I have managed to get a list of messages into a folder. 
Now when I delete a message I set a deleted flag. 
But the message still remains in place until I go to another folder and 
return, becouse the full list is then reloaded. 
Now the question is: How do I remove a message from the list and renew the 
list. 

Thank's in advance.
If my question isn't clear please ask some more information.
