your intervention is most welcome - thank you Graham -----------and ----------I've no idea what this is (yet).

Looks like the bubble in a spirit level. Hope if I am right its still Peters go or I'm not playing. Lol.

Think you might be right - hope not - still thinking!:)

Absolutely right! Well done Arthur!

Sorry to be so prompt replying Peter ;-)

Peter is it ok if I put in another one or have you got one now.

Please Arthur go right ahead as many times as you like - I am totally bereft of ideas right now.

Ok. thanks Peter. This should be simple as everyone should know what it is.

It's an SD (or memory) card innit?

Correct Peter. Thought it was not going to last long.

How's about this teaser, to fill in the gap?
