- go to a page that is long enough to create a vertical scrollbar (e.g. 
- use the scrollwheel (mine is a Logitech MouseWare v3.1.1)
==> the scrolling is much slower in Mozilla than in Nav4 and MacIE5

Is this the consequence of the fact that we scroll by ~1 line per event, 
while Nav4.x moves by ~2 and IE by ~3? [There's a bug about adjusting this
value -- bug 60986 -- which seems that it should be simple to fix].

it seems driver dependent, i think. the msft mouse gives us 3 'scroll events' at 
a time. logitech, i'm guessing, only gives us one. *shrug*.

It doesn't explain why with the same configuration on my machine (OS, mouse, 
driver), Nav4 scrolls at a regular speed, MacIE goes faster and Moz is really

i don't know of anyone else who has had problems. i'm at a loss to explain. could 
you try using the usboverdrive driver? that's what dagley does, i think, for his 
logitech mouse.

The M$ driver is a licensed version of the USB Overdrive driver so they should 
have the same behavior.  I also consider the default somewhat slow but I just 
changed the scroll wheel prefs in Mozilla to be 3 lines per scroll event rather 
than 1 and I'm happy with it.

Could you email me your driver?  I'll give it a try.

Before filing the bug, I tried different settings for the Scrolling Increment in 
the MouseWare control panel.  Same results.  IE and Nav4 scroll more for each 
click of the wheel than Moz.

Note that at the highest speed setting, Moz is as fast as the other ones (ie. 
each click of the wheel represents one page up or down).  At any other settings, 
it really is too slow.

You can DL USB Overdrive from usboverdrive.com

Note that the pref you want to change is a pref in Mozilla itself - there's a 
pref pane for scroll wheel line increments.

duh! I never noticed this pref before (I guess I ain't no Advanced used: I'm just 
a programmer, you know).
