Listbox MouseWheel Scroll Speed Faster on Windows?

SUMMARY: Listboxes on Windows scroll 3 times more aggressively…

The listbox.mousewheel event gives me a delta of 1 on my Mac when I move my mouse wheel one “step”. But on Windows 10, it gives me a delta of 3 which makes my apps feel rather aggressive.

Other non Xojo apps seem to scroll more or less the same between Mac and PC.

Is this 3x delta for Windows normal/expected?

Any reason I shouldn’t divide the delta by a third on Windows?
