Mouse & Touchpad sensitivity

I have a Dell Inspiron 16 7620 Computer:

Experience Windows Feature Experience Pack 1000.22636.1000.0

Question: Recently, and up to tonight, my Bluetooth mouse has been, I would say, extremely sensitive. Just moving the cursor (not clicking at all) highlights text, chooses programs (multiple instances in most cases). I basically have very little control over it. I uninstalled three drivers and shut down. When I restarted, the drivers were, of course, reloaded. I had no problems for about 20 or so minutes and the problem has resurfaced.

I have also had similar, if not the same, problems with the touch pad. I have not played with the drivers at all. I turned the touch pad off–until the mouse began giving me problems- I lost scrolling for one thing. Now both mouse and touch pad are active.

I’m not aware of adding any new programs or updates (but updates are mostly automatic).
I’m wondering if my use of the Opera browser has anything to do with this?… its just a feeling with no real basis attached.

I’d say I’ve had this problem for 4-5 days now.

Help?

Could be a physical issue with battery or buttons, so don’t overlook hardware.

Does the mouse play up in all programs?

Can you try a different mouse?

Thank you… I just changed the battery, but I don’t have a spare mouse.
Time will tell.

I’ve been poking around the internet and on the Dell site I found what appears to be a very strange (to me) cause and solution.
It appears that my Dell model, 7620, is prone to a buildup of static electricity in the touch pad.
It begins about 30 minutes after first use… which approximates my usage.
It tends to disappear, for a while, after a shut down and reboot (not necessarily just a restart).
Solution … baring sending the laptop back for ‘service’ … is to keep the room humidity up so the air doesn’t dry out, and/or shut the lid for a second or two.
This sounds a bit strange (again, to me), but it seems to ease or eliminate the problem.

In another day, after seeing how this works out, I’ll see about turning on my mouse again and see what happens. I don’t get the connection between the Bluetooth mouse and my touch pad as far as static electricity, but who knows.

Update: I had my touchpad replaced by Dell (warrantee, home visit!) about a week ago.
It has made all the difference!
I notice that the replacement touchpad is part of the palm rest and is a new design.
Both my touchpad and Bluetooth mouse have been well behaved for the past week.
