Wizard - I really did try to reach a conclusion to Waldos' question, as you will see from looking at the posts again - but what a lot of time consuming typing and posting it took, and I'm sure you'll appreciate the fact that I simply ran out of steam - the need to earn a living etc is also quite time consuming.
It was never my intention to be rude and post and then scarper, my respect for you all forbids that, but illness, my sons as well as my own, and quite a bit of bad fate / luck if you like, just knocked the stuffing out of me, and I just couldn't face coming back on for a while - simply didn't have the energy.
But hey! I've had me spinnach now and I'm O.K. for the moment.
