LuLa is one site!
I finished lunch, steeled myself to snapping point and pulled the camera from the cabinet.
Yep, the 'Lock' switch was turned on, simply because it always is, because I can only use the central focussing point due to manual lenses, and have locked the focus point to the centre. As a result, I forget about it and all of the other stuff that I have never wanted to use. Lesson learned! To be truthful, I didn't even see the thing earlier on during my battle with the machine.
I am now able to move the screen around exactly as I already could with images in the card.
Thany you all again - what would I do without you!
