KDE Control Center & MX1000 Laser Mouse

Hi, I have a Logitech MX 1000 Laser mouse and the KDE Control Center's Mouse section shows the tab that corresponds to this mouse. Unfortunately, all the controls there are disabled. Unfortunately, the actual mouse precision is not correct, and it makes it hard to control the mouse even though I've set the acceleration and threshold settings to rather extreme values. It's also very obvious when my settings are not in effect (during the login screen, e.g.), when the pointer flies all over the screen with only a little movement. Does anyone know why this section of the controls are inactive and what I must do to enable them? Thanks. Randall Schulz
