SteerMouse is the ONLY 3rd-party driver that works flawlessly across ALL of my apps, and with any mouse that I've bought. I have used all types of Logitech mice in the past, including the current one I'm using, the G700 Gaming Mouse, for Diablo 3. Mapping every single button to D3 is amazing!

Trusty ol' eMacster running 10.4.11 suddenly decided to tour Upper Bitblivion last month and has now been replaced by a shiny new (July 2011) Mac mini with 10.7.3 rolling. *w00t!*

One major issue: for the first time in 18 years, no right-button-assigned double-clickiness here. Only that feature – along with the old-fashioned, fat Mouse-in-a-Box form factor – fits my hand perfectly and prevents wrist aches. I've tried other meeces over the years; no joy. But now, no MouseWorks for Lion?! Not even a response to my customer-service email? Boo, Kensington! Enter SteerMouse [insert MacHead :::happy-dance::: here...]: comfort re-established.

Do I wish it didn't cost a week's food budget? Well, yeah. Was it worth it? Hell, yeah! (-:

I've been using this for 5 years on various Macs and various mice. Updates have all been free and I don't recall having any problems with it. Works fine with Lion and it recognizes all the buttons and sliders on my current Logitech mouse. For me it's an essential Mac utility.

I'm still patiently waiting and hoping for SteerMouse to be able one day to remap the two top left buttons (tracking speed change) on my Logitech G500.

SteerMouse is a great utility for empowering your mouse, but one little thing has always bothered me about it. It's just awfully peculiar that the System Preferences pane for SteerMouse does nothing except launch another application for setting the configurations. Why not make a normal preference pane that does it all right there? USB Overdrive does it the "normal" way now (it used to be exactly like SteerMouse) so there doesn't seem to be a sensible reason for SteerMouse to continue doing it the current way it does.

I also had problems with new version. Really couldn't get anything to work right. Even at highest setting, the cursor was very slow. Also,
couldn't get autoclose to work. I simply uninstalled and reinstalled the previous version, reset my values, and everything is fine again.
I really didn't have any problems with the previous version. Sometimes, I guess it's best to leave well enough alone.

The problem I had with 10.6.1 is the wake computer
When the computer was put to sleep, iMac 20" (2009) 2.66
with the power button, quickly push
is that the computer did not wake from sleep, by moving the mouse, or touching a key on the keyboard

I do not see this in the problem fixed with the new version 4.0.1

So I'll skip this update until it is confirmed this issue is resolved

Good software and I bought it because it enabled me to use a cordless Logitech mouse that does not otherwise have drivers on the Mac.

There are a couple things that annoy me about how buttons work Exposé, however. Maybe a workaround can be offered for these situations if the developer does not soon fix them:

I have my scroll wheel button set to Exposé all windows which it does, however only after I let up on the click. This makes using Exposé require two clicks to use rather than the one I used with a previous mouse: click once and hold while moving the mouse over the desired window and releasing to go to that window.

Also I have another button set to Exposé just my current application's windows, (in Steermouse it's set to replicate a Function key since I can't find another way to control Exposé thru Steermouse) but again, I can't hold down the mouse while I move it over the windows. If I do that, it just goes in and out, in and out of expose mode over and over.
