Windows 10: Touchpad not working, drags , slows, stops

I have an Acer Predator Helios - 300.I have tried for 2 months to get the touchpad to work properly, problem has only gotten worse.I try to update driver, uninstall touchpad and restart, get ACER drivers installed, Nothing has worked. I can hit Fn f7 - Fn f7 to turn touchpad off and on and i get about 10 seconds of functionality out of it.The touchpad disaster could have been caused by external sound controller w volume knob. I got 1 external USB volume control / output hub that was recognized as a mouse and plugging it in caused the touchpad not to work at al

Touchpad: Tap twice to drag

Here's how it works standardly:

1. Tap twice
2. Hold down on the second tap
3. Move around and you're dragging
4. Release finger to stop dragging

Here's what I like it to do:

1. Tap twice
2. Hold down on the second tap
3. Move around and you're dragging
4. Release finger
5. Reposition finger and continue dragging by flicking the touchpad some more
6. (repeat steps 4 & 5 as many times as desired)
7. Release finger and perform one addditional tap to stop dragging

That's what it used to be like in the Windows 7 era with most touchpads. Some people found it annoying and disabled it, but I welcomed it.

I know dragging continues when your finger reaches the touchpad edges, but that I find greatly irritating because it looses all sense of precision. This mechanism is stupendously irritating when trying to pixel-precise drag a trackbar, or when doing some
painting in photoshop on the go. Or just anything that requires precision.

So I'd like to disable "drag continues at touchpad edge" and enable "require additional tap to stop dragging".

So how can I do that?

If not possible, then please consider this a feature request.

Click and Drag using Touchpad Win 10 without separate Left Key

Hi Mike,

Your touchpad should be able to support click and drag, scroll, and other touchpad gestures. If you're unable to that, then verify if you have a precision touchpad. Just go to
Settings > Devices > Mouse & Touchpad. It should say Your PC has a precision touchpad under
Touchpad.

Below are some of the gestures it should support:

• Select an item by tapping on the touchpad.
• Scroll by placing two fingers on the touchpad and slide vertically or horizontally.
• Do a right-click by tapping the touchpad with two fingers.
• Drag an open window by double-tapping and dragging from the title bar.

In case you're still unable to click and drag or do other touchpad gestures, then we suggest that you get in touch with your computer manufacturer so they can further check on the case.

Update us on how it goes.

Regards.
