Thanks.
I am coming to loathe it, to be honest, and wish to strangle it regularly.
As it happens, I rarely check posts before pressing "post reply", and I really detest the controlling tendency of that thing to decide it knows better than I do what I wish to write.
However, there is another issue, which is, as I age, I find that I am not hitting each key with equal strength, (the location of some letters means that they are not struck correctly), and therefore, sometimes a key I have tapped with insufficient strength hasn't registered at all, and that is when the stupid auto-correct decides to substitute something else.
Anyway, thanks for drawing my attention to this; the error has been identified, edited and corrected.
