I really don't know what Cocoa does as I don't have a Mac. However, with GTK+, Qt and Windows application the amount of scroll between using the scroll buttons and scroll appears to have a 1:3 ratio. I tested multiple applications and they all seem to follow this ratio.

I just searched the internet on further information on the behaviour of scrollWheel:, but there doesn't seem to be much. In GNUstep just as Cocoa the default vertical line scroll (_vLineScroll) is set to 10. And we use this value not only for scrollLineDown: and scrollLineUp: but also in scrollWheel:. Maybe this is wrong?

This is not a bug but something that sometimes gets on my nerves. Right now, whenever you use the scroll wheel to scroll inside a GNUstep application the field isn't scrolled the "standard" amount. I use that work loosely, here. On Windows, GTK+ and Qt, one scroll wheel unit on my mouse scrolls the text view (of any other type of view) anywhere from 3 - 5 lines, on GNUstep I get, at best, 3/4 of a line. This makes it extremely fustrating to use the mouse's scroll wheel.

Let me know if further clarification is needed.
