Backspace won't work

[Dave Neve]

Hi

I got into some really deep water with a software that installs itself onto
Word using macros

Just when I thought everything was ok again, I have lost my 'backspace'
button and can't efface letters in Word

I know it isn't the button on the keyboard that has gone wrong as it is
working now in Outlook and it works in Windows (for instance when I type my
password)

But it is blocked in Word

Incidentally, when I type a letters n Word, the first letter has a line
under it which I don't remember being there before

Any ideas what is going on please?

Thanks

Dave Neve
