K mail question

[charlie bullen]

I am using Kmail at work with 3 email accounts, 2 work related that I have set 
to remove mail from the server when I download it, an 1 personal account that 
I use for Plug among other things. This account is set to leave mail on the 
server as I want to be able to retrieve these messages at home also. 

All of a sudden, when i retrieve mail on my personal account it is not marked 
as retrieved so each time I download mail I get the same stuff over and over. 
Any Ideas?
