I've just had a thought (no...nothing like that!)
Is it on the laptop that the options are greyed out.Is it a company provided laptop,does it run Nt or windows.If its nt what level is your access(user or admin)If its just user are users enabled to alter things like this or do you need to be admin level to do it.As you can see I can think of the questions it's the answers that are more difficult.
