34431 - Scroll wheel on IBM thinkpad doesn't work

Status: VERIFIED DUPLICATE of bug 38284

(Core Graveyard :: Tracking, defect, P3)

Description

[Kevin Roquemore]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; m14)
BuildID:    2000040308

The scroll feature on the IBM thinkpad doesn't scroll pages in Mozilla. On this
computer, you access the scroll feature by pressing a special scroll button and
use the Pointing Stick to pull up and down in the page. In Mozilla, this feature
doesn't work, but it does work in Navigator 4.08.

Reproducible: Always
Steps to Reproduce:
1.In preferences, choose Scroll 1 line when using Mouse Wheel
2.Go to any page that has more than 1 screenful of information
3.Press the scroll button and pull on the pointing stick.

Actual Results:  Nothing happens

Expected Results:  Page should have scrolled 1 line at a time

[e-mail] - are you still seeing this problem with recent builds of 
Mozilla?

Yes, problem still manifests in Milestone 15 (B: 20000041805). Unfortunately, I
haven't been able to test on more recent builds 'cuz I get a crash while trying
to setup proxies.

I have a theory (so far - unconfirmed): I think the Scroll feature on the
Thinkpad may be equivalent to pressing and holding the scroll wheel while
moving the mouse on an MS mouse. Is it possible that Mozilla is looking for the
"Spin-The-Wheel" action but not looking for the "Hold-And-Pull" action?

You're right -- that action causes "panning" with native widgets, and we don't
support that in Mozilla.  I believe there's a "helpwanted" bug on implementing
it.
