Nyk, that's because I'm a Flange & only just realised what you meant after looking at your spelling & the seemingly inappropriate use (at first read) of a capital letter. I'm now up to speed (it's a better day today, I can actually spot subtlety) & can appreciate your subtle humour to it's full extent :0) God I can be right knob at times :0) And don't you dare all rush in to agree with me !?!?!?
