All is not lost. The wonderful Lee has sorted my ailing computer. Let's hear it for him!
OK so I need a new computer, but my hard disk is safe, so the work is safe. One big thank you to Lee, who, incidently, used to play in the same band as me.
Meanwhile, I have it on good authority that some people want to add comments etc to my blog but are having problems doing so. Keep trying you people. Keep trying.
It's lonely out here
