Dear Maintainer,
Scrollbars appear to inherit the same settings as configuration sliders. It may
be a good idea to use gtk-primary-button-warps-slider=1 as a default for
settings panels (e.g. screenlock timeout etc.) but it is a very bad idea to use
the same settings for scrollbars.
Expected behaviour for scrollbars in pretty much all software (since Motif was
invented, yes I'm old enough to remember those days) is not to warp. GTK should
not (re)introduce such inferior and nonstandard scrollbar behaviour by default.
Andrew.
