Ok, thanks, Milo. I reckon the chap/chapess in the vid. has done it before! The external monitor I'm hooked up to is a 17'' emachines 700G, not wide screen. I'm actually finding the lack of wide screen is not a bother. The screen height is greater than the HP built in one and for my DTP work this is an advantage, I'm finding.
Now maybe I can revitalise my goal of networking. The other thread may yet have another post from me. Cheers.
