Status: UNCONFIRMED

(Core :: Widget: Win32, defect)

Steps to reproduce:

On Deviantart.com, I click one of the images on the front page. When the page loads I press the middle scroll button (on Lenovo laptop) and apply pressure to the left of the trackpoint in order to scroll the page horizontally.

On Facebook.com, I log in, click on a friend's album, and click on a photo in the album. When the photo pops up, I press the middle scroll button (on Lenovo laptop) and apply pressure to the trackpoint in order to scroll the page horizontally.


Actual results:

Instead of scrolling the page horizontally, the webpages that I described in the steps to reproduce catch the horizontal scroll event as if I had pressed the left/right arrow keys.

On Facebook.com, while viewing a photo, I will be taken to the next photo in the album (as if I had pressed the right arrow key), or if I try to scroll horizontally to the left, I will be taken to the previous photo in the album (as if I had pressed the left arrow key). On Deviantart.com, the behavior is the same as on Facebook.com.


Expected results:

The horizontal scroll should not have been treated as a left/right arrow key press.

The behavior depends on your mouse driver. It seems that it emulates a left/right arrow for scrolling.

@Matthias No, I don't think so. The bug is not reproduce-able in IE 8, Chrome 13, Opera 11, nor Safari for Windows v5. No other program treats my horizontal scroll as left/right arrow keys except Firefox.

Firefox doesn't use native windows scrollbars and the mouse drivers have all kind of hacks for the scrolling functionality because there is no windows API for scrolling.

I found this via a google search : http://rayli.net/blog/2011/07/touchpad-scroll-not-working-in-firefox-on-thinkpad/ . Please make sure that you have the latest driver installed.
