OK so I tried this and then got stuck when after clicking the `Services' Tab there was no `hide all Microsoft services' on the list.

So..... I decided to go back to the drawing board and think laterally.
I created a third user with a similar name to User 2 who was locked. I then set up User 3 with the Email a/c from User 2. (Windows Live Mail) Essentially I morphed User 2 into User 3. I then deleted User 2. He did lose his bookmarks but as he didn't have many this was no biggie. So far this is working well with no probs. I have no idea what caused the `frozen pointer' for User 2. I just hope it doesn't happen again.
So now I have built some new synapses in my brain I am free to go on with my own stuff. Thanks so much for your help and fast response
