Mouse and curser with a mind of their own.
I have an Acer laptop which is fine for what I need except that, just recently, the mouse screen pointer has developed a mind of its own and wanders off to a different part of the screen.
Also, when writing any script at all, I'll find that what I am writing will suddenly appear where the pointer happens to be at that time (usually somewhere within the previous paragraph), not continuing the sentence.
I am sure I've heard of this happening before but can't remember what the solution was.
Any ideas please?
