Patch part 6 of bug 392188 landed using the wrong attribute in scrollbar.xml (http://hg.mozilla.org/mozilla-central/rev/f1cd1c78ebd3) - allowclickthrough vs. clickthrough. Does this mean that part of bug 404267 was not fixed? Or was that change not necessary?

Comment on attachment 608170 [details] [diff] [review] patch Good catch! It means that scrollbars in trees weren't clickable / draggable in inactive windows, since trees have clickthrough="never" and scrollbars failed to override clickthrough on themselves. (The right behavior is that scrollbars should always be clickable / draggable on background windows, regardless of whether they're in a clickthrough container.) Scrollbars in normal (non-tree) scrollboxes correctly have clickthrough="always" set on them by nsGfxScrollFrame.cpp.
