6633 - Scrolling up or down from the keyboard also scrolls to left

Status: VERIFIED WORKSFORME

(Core :: Layout, defect, P3)

Description

[Jonathan Lennox]

When I scroll up or down with the keyboard in apprunner (using PageUp, PageDown,
or space) on a page which is wider than my current screen, the display jumps so
that it is horizontally scrolled all the way to the left.

I noticed this with the default start-up page,
http://www.mozilla.org/quality/smoketests/, because it lays out somewhat wider
than the the default apprunner window, so I had to scroll to the right to view
the content rather than the Mozilla sidebar.  When I hit page-down, the content
was again half-obscured off the right-hand side of the page.

I don't know if this properly goes in "Layout", but I wasn't sure what other
component would be applicable to it.  (It depends somewhat on what's causing the
problem, I suppose.)

This is a SeaMonkey tree of 05/17/99 11:44:23 PDT, compiled and running on
FreeBSD 3.1-STABLE, configured as "CC=egcc CXX=eg++ ./configure
--enable-mailnews".

More event/scrolling problems that you may already be aware of. Tom, if these
shouldn't go to you, please let me know.

Separate the scrolling down function from making the horizontal scroll to the
left

reproducible on mac; change platform/os to ALL; reassign to beard and cc michaelp
since they worked on the scrolling code which is where the bug actually is.
ScrollByPages() calls ScrollTo with 0 rather than the current position.
