I seem to recall some grief against Logitech and their driver implementation (or stuff being placed at the System level) which upset users? What was the outcome of that? Using SteerMouse, I have the top-center button mapped to Expose and the "minus" button mapped to switch application. See below.) I've never found this useful. (EDIT: they work in OS X, but SteerMouse disables them.

In Windows the buttons above and below the scroll wheel (on the 518, not the 510) change the sensitivity of the mouse on the fly. I have mine set to scroll full pages when it's pushed down. It also lets you make a distinction between just using the scroll wheel, and using it when you've clicked it first. SteerMouse lets you map the mouse buttons to different functions in different applications as well. USB Overdrive works as well, but I find SteerMouse easier to use, more flexible, and more reliable.

() It's a little pricey, given that this functionality should really be built into Mac OS X, but it's worth it. I have my side buttons mapped to Back/Forward, using SteerMouse. However, I find Mac OS X's mouse mapping options to be terribly limited. Only the ridiculously expensive Logitech G series is still corded, and only the $100 G9 is both corded and has the "MicroGear™ Scroll Wheel." :rolleyes: I gather some of the newer Logitechs do this, like the Revolution, but I see no point in having a cordless mouse. It would be much nicer if it just freewheeled. The only complaint I have is the clicky scroll wheel. For all intents and purposes, they're identical. The increased sensitivity of the 518 is hardly noticeable, though. 1600 dpi) and has hardware sensitivity control buttons. The 518 is slightly lighter, "twice" as sensitive (800 dpi vs. The 510 came in red and blue, the 518 in silver. It looks like you might actually have an MX510. :) You can pry mine from my cold, dead fingers. A favorite of mouse-nerds everywhere (), for good reason: it's indisputably the greatest mouse ever made.
