My Logitech Optical TrackMan's additional buttons often suddenly stops working in the middle of my work. The only buttons still normal are the left and right buttons together with the scrolling-wheel. It seems like MouseWare is losing the key-mappings and "degrading" the mouse to an ordinary two- or three button mouse without any of the special functions normally assigned to the keys. I had the same problem with my old Logitech MX700 and the only solution I have is to simply reboot my computer and everything is back to normal again. Does anyone know what may be causing this problem and what I can do to fix it?
THANKS!
