LAINSNAVI I've had three different Logitech mice since I've gotten OS X. Up until the version prior to this, There was an issue with mouse tracking if you logged out and back in. I was glad to see this was fixed by removing the option from the driver and relying only on OS X's built-in mouse tracking. With this new release, you're now able to change a button's function per application. I've been wanting this for years! I didn't want to spend money on some third party application to do this, so I just lived with it. I'm not sure why people have so many problems with Logitech's driver. The only problem I've *ever* had in the past 4 years is the mouse tracking issue. And I've had three different Logitech mice in that timeframe. The driver works wonderfully for me. I'm currently using a MX500. I know the Optical Click mouse works fine with it as well. I highly recommend using this driver. (Version 2.1.1) |
