Sometimes a click in the scrollbar area does scroll two pages instead of one.

The page up/down keys do work ok.

I guess it's a very different problem to Bug 416312

Reproducible: Sometimes

these are typically mouse hardware issues?  Do you still see the problem with a different mouse?

Comment 2

[Martin Trautmann]

I never checked with a mouse, and a click should not depend on the mouse, while a scroll might do. It was an iBook (now MacBook Pro, now 10.6) with a trackpad.

However, the problem "fixed itself"

I unchecked one of the options (use autoscrolling? use smooth scrolling?) I wouldn't have expected this option to change single page scrolling to double page scrolling.

So the topic might belong to those advanced options.
