I have an Acer E15 laptop with a touchpad (Elan). From time to time I find it's doing odd things in Excel, such as when I tap to click on a box and then move the cursor it selects all the cells as though I've done click and drag. It seems tap to click has been turned off (although in the settings it seems to be on still). Problem is resolved only by rebooting. More recently the cursor decides randomly to wander - at first seeming to be lagging but then wandering around the screen by itself for a while before coming to rest.
Any ideas?

By the way, although the info below says defender is disabled, it does say it's on and working on my system.

Hi,

When touchpad hardware is faulty or damaged, it can manifest in cursor jump and click locks etc.
- Try turning the touch sensitivity as low as possible using the touchpads settings dialog - it should be located in the Control Panel under Mouse.
- Make sure the touchpad surface is clean and free of any oils, moisture etc, If anything residual is present, clean it with a microfiber or similar cloth. Avoid using any cleaning fluids.
- Disable the touchpad in the control panel and attach a mouse. If the behavior continues with the touchpad disabled, then the problem is more likely software related/virus etc.

Cheers,
S

I can't quite work out if it's faulty hardware why it's sometime fine and other times not, nor why the problem goes away if the laptop's rebooted.

I don't have a mouse to try, nor anything about mouse sensitivity.
