Most people would regard the Gorse Fox as relatively competent when dealing with technology (or at least computers). After all - he has been working with IT for 42 years now. Some skills should have evolved during that time.
Fiddling around yesterday morning GF noticed an option on his laptop that he had not tried before and being inquisitive, he selected the "Extend screen" option. (He had been thoughtful enough to plug a second monitor into the device first). Voila, his laptop screen-estate rolled out to incorporate the second screen. Brilliant, yes; but why has he only just discovered this!
