Thanks for reaching out to us. I would suggest you to perform the steps in the link : https://dell.to/2Vgss2H and share the findings.
In addition, for my reference, please click on the message tab next to your avatar– click “New Message” & search for my Dell username (DCFAdmin) & send a private message with the service tag, registered name & email address.
I am having this problem too! I'm in the middle of doing something and then my mouse moves around opening and closing tabs.. very annoying. Spent a lot of money on this laptop for this to be happening every time I use it.
Dell, what can i do to stop this from happening again?
