(Modified) It change as much as -14x (with heavy movement) but typically as much as -3x in what appears to be -1 increments in both cases

Up +1 increment / Down - 1 increment (with typical +/-30-46ish on regular movement and +/-146ish on extreme movement, in both +/- and keeping the mouse pointer within the control and just after up/down movement for vertical scrolling will +/- to whatever maximum value then return to either 2/-2 delta after scroll action.

Looks like it's one of the rare cases of Accumulating Deltas (these things are hardware dependent). My old procedures covered that, but now I switched to tB's built-in wheel handler, which apparently fails at these special cases. I'll try to work around it.

I've sent a short MP4 video (256K) to support directly.

Thanks.

I tried a fix in the Customize Toolbar dialog. Next beta. If it works I'll add it everywhere of course.

It works. BUT:

In the list of "Available buttons" from data items "Separator" to "Step Mode" the flow is jittery, jumpy, or sluggish. like it is building the icons or something. It's interesting how if I click on and select the vertical scroll and drag it, the flow of the data items is perfect and lightning fast.

It almost seems like the vertical scrolling number of items scrolled is linked to how many items are in the list. List:"Available buttons" has a lower number of items scrolled (seems like lowest is 2 items scrollable) relative to the List:"Current buttons" which seems to want to scroll at least 4 items at the smallest vertical scroll movement.

It's doable compared to not working at all.

I don't know if the Accumulating Deltas is a MacBook AArch64 or if it is Parallels --> Windows AArch64 thing.

I'm curious how the above implementation effects the list control in "Configuration" > "Jump to Settings..." > "List of All Settings"

Hm. That means I didn't get it right. The smallest vertical scroll movement should be 6. Always.

I'll have a look at it again later.
