Trackpoint scrollwheel not working

[Magister]

I have a Lenovo keyboard with trackpoint (small red thinggy between GHB keys), there is a Lenovo driver to activate a feature that you can press the middle button and move the trackpoint up or down to have the same behaviour as a scrollwhell. It works everywhere in Windows, in all apps, but not in TC.

In TC when I press the middle button it changes the icon to the scrollwheel one, but pushing up or down does nothing. Pushing left or right makes all kind of strange behaviour with window scrooling and I cannot stop it.

Do you run TC as administrator?

Yes I'm running as Administrator, but even as a non-admin it does not work

I suggest to play with the settings in the Synaptics (?) driver and see if that changes anything. Do that in a TC that is not running elevated (as admin).

I tried before it changes nothing. TC is written in Delphi? Maybe it does not react on the events like others apps? Can Christian give me a version or a trick to log windows events? Obviously I understand it might be a Lenovo driver glitch, but really it works in each and every application I tried in windows. TC is the only one not working

It may be relative to not receiving the EN_HSCROLL event? @ghisler how can we debug this?

Others people seems to had problem with scrollwheel in Delphi too

Well, which device and Windows version do you have? Is the driver for the trackpoint really installed?

Is the trackpoint a Synaptics device or a different one? My brother just told me that he had contact with an older Lenovo device that had an ALPS trackpoint (or UltraNav, which also includes the touchpad) where scrolling also didn't work. And the culprit is most likely the driver. Synaptics devices (like the one in my ThinkPad T43) work fine.

It looks ike it's a Chicony one, and the program that is used to catch the middle button and emulate mousewheel, seems to be called hscrollfun.exe.

I have latest Win11Pro and the device is a Lenovo Thinkpad Trackpoint Keyboard II.

Driver may be the prob, but the feature is working in all and every apps I tested, except TC.

I'm not handling scroll events myself in listboxes like the file lists, that's all done by the Windows LISTBOX control. It doesn't depend on the used programming language.

I understand Christian, but there's something odd then because it's the only app misbehaving

[Dalai]

Ah, it's just the keyboard. Up until now I thought you have a laptop using such a keyboard. I misunderstood that.

I suggest to try in Windows Safe Mode and/or to uninstall the driver if scrolling works without it.
