Hi there,

A friend has a new Toshiba Sat laptop which has Word 2003 installed and he has this
odd problem that sometimes when he is typing in Word unbeknown to him his cursor
jumps to a previous point in a paragraph and as he types he is then typing in the
wrong place this doesn't happen all the time just occasionally but enough to be
very annoying.

He has tried all the obvious things like checking if he is hitting a wrong key but
can't seem to pinpoint this strange behaviour to anything he is doing.

Any pointers would be much appreciated.

Many thanks, Tim.
