(Gecko/20031225).

3.

Interesting.  Looks like all the scroll events are being delivered to one of the
menus on the left.  Not sure if that's intentional or not.  The widget system
certainly is delivering them so this doesn't appear to be down at the widget
layer.  Probably something higher in the view manager or dom?

Hrr. Jesiah, can you narrow down the regression further?

Using Mozilla CVS I narrowed it down to 15-17 Sep 2003 00:00 PST.  This seems
odd as Firebird 7's modified dates on the servers are Oct 15. 
Note:  that after and including the 17th this bug will only show up in certin
places but not the whole screen like more current versions of mozilla.  When you
move the mouse a few inches it will start scrolling again.

Jesiah, THANKS!! I suspect bug 69355.

Jesiah, can you try producing a small testcase? I suspect it involves the use of
"overflow:hidden". One thing to try would be removing all overflow:hidden from
the test page(s) you already have and see if that makes the bug go away.

okay, I'm pretty sure this is overflow:hidden elements eating the scroll events
(because they're now a special case of scrollable elements). But I can't easily
see exactly what's going on here because I don't have a wheel mouse. Maybe David
can help...

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
