Windows 10: Tap in the touchpad is not working

In my laptop tap option is not working.

Lenovo T400 touchpad tapping and buttons fail

I recently made a mistake. I loaded the latest Synaptic touchpad to this T400 attempting to fix 'zoom' capability. Only afterwards I noticed T400 is not on the approved list. So I rolled back (also redownloaded, also reapplied old driver). The current situation is the cursor works fine but tapping and buttons do not work. Also note that USB mouse via HID compliant driver works fine.

I don't think it is related to the Windows version (currently on 1903) since I booted from Kyhi's 1703 rescue disk and the problem persists. What suggestions can this forum provide?

Thanks in advance

 

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.

 

Touchpad tap configured as "mouse back button" not working in Explorer

I have a ThinkPad T480 laptop, using a Synaptics touchpad. I use the built-in Windows 10 touchpad settings to configure the tap functionality.

I configured the touchpad to function as a "mouse back button" when I tap it with three fingers. It works fine in Firefox but it does not work at all in Windows Explorer (i.e., browsing files on my computer.)

Touch pad scrolling works fine, even in Windows Explorer.

Interestingly, I can get it to work as long as Explorer isn't focused. So, for example, if I click an empty part of the taskbar and then put the cursor over an Explorer window - without clicking it - then I do a three-finger tap, Explorer successfully goes back.

One other interesting observation: if I set three-finger tap to something else (say, Action Center), it does work in Explorer. This suggests that the problem is not Explorer failing to recognize any taps - just SPECIFICALLY back-button tap functionality.

Also, I tried setting two- and four-finger taps as mouse back button functionality but it doesn't work for those either, meaning the problem is not specific to three-finger taps.

Any ideas?
