Had one of those things for years.Had to send mine in years ago (under warranty) because it lost calibration.It would not go back to center no matter what I did in the config.I gave up on mine when Vista 64 came out.It would no longer let me map 1/2 the buttons.I think it's a problem with the 64 bit OS.Works fine on a 32 bit machine though.
Logitech software fucking sucks.Even the new LGS software for my keyboard and mouse refuses to load at startup without me physically telling it to start every time I restart my PC.Have to click on the LGS icon in my start menu every time.
Those things are Really OLD.I got mine when Battlefield 1942 was released way back in 2002 and they haven't changed anything about them.I know there still selling them but You have to remember that those things were originally designed to work with Windows 98, Windows 2000, Windows Me and Windows XP.
