Hi Duncan   

Thanks for the reply i think it may be as you suggest a permissions
problem but it is proving to be hell to sort out   every thing was fine
untill i accepted the update to the latest Xorg server  then  well 


Ok  well i am going to be out all day tomorrow fishing so will try to
solve it monday evening and get back to you then .


Thanks Pete ..
