TWiMC,
I've used Logitech devices at Rosendin Electric as long as I can remember. Settings for the keyboard and mouse used to be in one convenient application. Now the mouse is no longer a part of the software used to adjust or change the settings. I have to download the 'options' software for the mouse. The only problem with that is the software is no longer stored in the hidden icons tray and when I do implement settings using the software, they aren't permanent; I have to keep opening the software an re-implement the settings I want. Over and over and over. What happened Logitech?
