Clever stuff far beyond anything I can manage, very impressive. I did, however, notice that you have some CDs on the window sill. The other day I opened some unused CD-Rs (left on the window sill) to find that the light had penetrated through a small slot in the case leaving a black mark. None of them were usable.
Thanks Ray. And, re the CDs, I'll move them, although I imagine they're all pretty knackered by now!! Nothing important on them, just my life's work!! Just try and imagine a world without my steel playing on it...not difficult, I suppose.
