Share Screen on ARD Does not work unless the user is logged on

Question

Since Upgrading to Lion, I have been unable to get the Share Screen in Apple Remote Desktop fuction working from Any machine. All Clients are on the latest agent of ARD and are completely upto date.
When i try running the task when the clients are at the login screen, They just get a grey bar at the top of their screens. So it is recieveing the share screen task but not updating the image on the client machines.
The only alternative is to get the users to login before we start the share screen task in ARD.  The issue with this is teachers prefer to be able to put work onto the screens before the pupils have a chance to log in and mess around on the machines.
I have tried downgrading to ARDagent 3.4 on the clients, i have also tried turning off remote management and enabling again, like some have suggested.
It would be great if someone has found a solution to this.
Thanks.
