example, 1.3a)? if so, please comment again with details. if not, please resolve

i have tested on 2002123005 using these steps :-
1. make the window narrower until horizontal scroll appears
2. hover the mouse on horizontal scroll
3. scroll the mouse wheel
4. the document scrolls vertically

sorry for the spam, just a few more to say...

1. using m.o nightly.
2. Other GTK apps will scroll horizontally when the mouse is hovering on
horizontal scrollbar and then the mouse wheel is scrolled.

It seems that this bug is still open.
Tried with mozilla 1.4b, and it doesn't work. I use gtk2.

but I want to add that horizontal scrolling is possible when you got mouse with
7 buttons (as XFree count them : 4 5 normal wheel, 6 7 second wheel or back/next
as you prefer).

PLEASE COULD SOMEONE PASS IT TO NEW ?
(I ve tested it and it is still open )

If I understand right what's going on, scroll events are handled early by
mozilla and bypass the normal event flow: normally the scrollbar reacts to them
by scrolling to the right and moving the document along with it. Here mozilla
receives the scroll event, decides if it should move and how much, and asks back
the document and the scrollbar to move.
This complicaion may be useful to provide smooth scrolling. So there are two
ways to fix this: inherit from the gtk scrollbar to get a scrollbar with smooth
scrolling; this would have been sensible in the beginning as it makes event
propagation more straightforward but maybe is not worth the effort now; or make
mozilla understand scroll events on horizontall scrollbars, see bug 71464.

As this bug explicitely wants horizontal movement when hovering above the
horizontal scrollbar this is a dupe of bug 71464 (which is for all platforms) as
OnyxG7 already discovered.
