Peter:

Hoping some-one can help me. I have run a process and put it into the background. I have then logged off and then logged back on later but i can not get the process to come back to the foreground. Does anyone know how to do it? Any help would be extremely gratefully received.

Off the top of my head, no. I'm not sure you can. Have you considered using screen and running the process in that if you need to regain control of it?
