632654 - Scrolling gesture on Alps touchpad zooms instead of scrolling

Status: RESOLVED FIXED

(Core :: Widget: Win32, defect)

Description

[Ryan VanderMeulen [:RyanVM]]

This is a regression from bug 593372. By default, my touchpad now zooms when I attempt to scroll. I have an HP dv4t with Windows 7 x64 with an Alps touchpad. Changing the ui.elantech_gesture_hack.enabled pref from -1 to 0 fixes the problem.

Elantech registry entries weren't present on Ryan's laptop, so that isn't the cause.

I'm seeing this with my Logitech mouse on my desktop with the latest hourly (http://hg.mozilla.org/mozilla-central/rev/fa1a4b6abff0).  Attempting to scroll the page with my scrollwheel is causing the zoom level to change.  I have the Logitech SetPoint software installed.  This is all on Windows 7 x64.

Doug: does setting ui.elantech_gesture_hack.enabled to 0 fix it?

If so, can you debug to find out why IsObsoleteElantechDriver is returning true?

No, setting ui.elantech_gesture_hacks.enabled to 0 does not have any effect (and I did restart Fx just to be sure).
