- go to a page that is long enough to create a vertical scrollbar (e.g. http://www.apple.com/ibook/) - 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 sluggish.
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). WORKSFORME
May God have mercy on us all. The 212 bug spam-o-rama is Now!
FWIW: fix for bug 127362 was just checked in.
