Mandriva 2010 logging out when using kmail
Fairly new to Mandriva and linux in general - they are using it in my workplace and I have installed it at home on an old machine.
running Mandriva Linux release 2010.0 (Official) for i586
Kernel 18.104.22.168-desktop-1mnb on an i686
While using kmail, (shortcuts to mark as read/unread or when moving emails to a folder in particular), Mandriva will auto logout. Sometimes it happens several times per week and other times it can go a week or so without any problems. It is getting quite frustrating when in the middle of working through a stack of emails and it just logs out.
I have searched for a solution on various forums and google, but have not found anything. Any help would be appreciated.
