Thanks for the info about the thunder Dai, you have confirmed my fears. I was not sure whether I was being paranoid or not.

And thanks Dave, I have checked mine just in case and it is in good order. I use the proper extensions with surge protectors but as most of my cable runs (safely) under some furnture and the plugs for my computer and hi-fi equimpent are hidden by a speaker, I tend to forget about them.

I suppose another point on electrical safety is that the plugs for all my elecrical equipment are fitted with the correct rating of fuses.
