Hi etbsb

Just a little update.

It was a PICNIC.    ;-)

Having noticed the mouse related behaviour,
and pressing case, or keyboard hard,
also affected the corruption,
it turns out it's an earthing/earth leakage issue.

Slackened off two of the keyboard retaining screws 
and the problem disappeared.

Seems I'd possibly overtightened them,
or it was plastic creep with age.
