IBobi,
Thanks for your responses but your last one (#11) does not wash with me and, I'm sure, others either.
Just recently, a major retailer here had been having problems with their 'clever' new IT idea.
The girls on the complaint line had been instructed to suggest to complainants that they change to Google Chrome. (Ahem!)
Well, of course they've now fixed things so that their setup is now compatible with all major browsers. (Fancy that).
An analogy would be asking the holder of one particular bank's credit card to switch to another because the 'new' system can't cope.
See what I'm getting at?
