I've only been using OSX for a week now and I've been looking all over for a way to set OSX to scroll one line at a time instead of 12 or so with a scroll wheel. I have the Intellidrivers loaded along with USB Overdrive. I set Overdrive to scroll up/down one line at a time, but it doesn't seem to work. Surely someone has a way?

What mouse/trackball are you using?

The mouse wheel usually scrolls about one line. Maybe the fact that you have two additional mouse drivers installed has something to do with your problem. Why did you do that?

Without any particular drivers installed, the Logitech mouse on this computer scrolls just one line at a time. (per wheel notch)

Try disabling either software, or both?

I'm using an Intellimouse Optical 1.1. I uninstalled the Microsoft driver and got the USBOverdrive to work but even if I set the scroll to 1 line at a time, it scrolls three and that seems to be the best I can find.

*update* It appears that only Firefox (and probably some others) scrolls three lines at a time whereas Finder and Safari scroll one. I'm assuming this is a Carbon issue?

The Finder is Carbon; Safari is Cocoa. Both work correctly. So how is this a Carbon issue?

I've only been using a mac for a week so I don't know the difference, I just read on the USBOverdrive page that some carbon apps don't support wheel scrolling properly.

I'm sorry. I thought you were one of the Cocoa zealots.

Carbon supports the mouse wheel very well with Carbon Events. Carbon Events are new in Mac OS X, so some Carbon applications ported over from OS 9 might not yet support them, but almost all do now these days.

The issue is probably unique to Firefox or the Mozilla browsers. It's unrelated to Carbon.

Cool, I am thinking the same thing now that everything but Firefox seems to scroll correctly. Thanks!

The 'Advanced' prefs in Firefox have settings called 'auto scrolling' and 'smooth scrolling' that, for me, seem to increase the scroll rate when turned on.
