Correct, I just now tested it. It's the moving process. If I move any message 
after reading it, then the counter goes mad. I had 3 msgs and I deleted 1st 
one, moved the 2nd one, it supposed to say 1 of 1, instead, IMP is saying 2 of 
2, and even the back arrow on the corner is also there to go to the previous 
message when there is no previous message in the INBOX. When I click on the 
previous msg button it gives me the following error on the error msg 
box: "There was an error viewing the requested message.". and it gives the 
warnings that I was talking about if I delete the msg.

So, I think we traced the problem back. When one message is moved it IMP does 
not reset the counter to the actual number of mails in the folder.

Comments that please.
