R##... and Malcolm,
Thanks to you both.
Pleased that I am not alone with this problem and as my machine does not need a login password etc I will apply my own 'fix':
I will look the other way while it does its thing in this regard.
Don't know why they can't leave the bloody updates alone for more than five minutes. The keystrokes to achieve inverted ('.....') commas seems another victim of Windows fiddling as it used to be a stand alone keystroke like every other but now needs to be followed by a spacebar as otherwise one gets the next character with an accent/umlaut mark (á/ä) of some sort.
Regards
