>>I'm not up-to-date with the latest Logitech Bluetooth devices, but my general understanding is Logitech supplies a complete end-to-end software package/suite for all parts involved, and which is optimized for use with their hardware. If a Logitech tech support person tells you not to install that software, or the software is otherwise known to be buggy I suppose it should be avoided. But, it might be worth at least trying it - IME it uninstalls cleanly if it doesn't work and you need to remove it later.

>The one I have is MX™ Revolution. The keyboard is Cordless Desktop MX™ 5500 Revolution. I never had any problem with the keyboard. I am downloading the SetPoint 6.15 software version 6.15.25. This is from 07/20/2010. The detail page is at http://www.logitech.com/en-ca/428/130?selectedcrid=428&selectedcid=130&WT.z_sp=Product&osid=14&bit=64.


I've had to uninstall setpoint software to fix problems on my mom's laptop (mostly sleep and autorestart issues) so many times that I bought her a new mouse. It drove me nuts. She liked her logitech mouse though is constantly using it again and then calling me for help when her screen saver quits working and then her laptop stops going into powersave mode.

I've never had any wireless mouse be reliable without the usb receiver on the side (laptop) or front (pc).

I will NEVER EVER EVER buy a logitech mouse again after my own and my mother's experiences. The first thing I did was hit their forums for resolutions and they are filled with issues that cannot be resolved easily.
