i recently tried to upgrade to win8, it was a disaster.. dell had to reset my laptop to factory settings. my keyboard is a mess.. i can be typing and then next i will be on another line, it will do things like highlight, cursor disappears, or it will remove the word and type something different.. ive checked everything i can think of... what is the problem????
Could it be the sensitivity of the touchpad is set too high? IAC, go to the Dell site and download the latest drivers.
What model is this? Mine did the same thing. It is a driver issue. You need to get help from dell.
