Notification for Requester-Replies does not work

I have some troube with the Option "Alert(or Notify) Technician by Email when there is a new reply from the requester":

We have set this option to have our Technicians informed about incomming replies to existing Workorders. Normally the content-message of the reply is shown in the Notification.

After the Upgrade to 6.0 it looks like that only the content-message of the main workorder is included in the Notification - not the message from the reply.

I need a solution for this issue really soon. During weekends we live with this function because most of my technicians have only access using their blackberries. So they need all necessary informations in the notifications.

Thanks
Florian
