My old Logitech MouseMan decided it was finally going to start dying (it was sticking every so often and just being annoying), so I picked up an MX510. Very cool mouse, almost as comfortable as my MouseMan was. Anyone else using this mouse on Linux? I can't seem to get the side buttons to work. Scroll-wheel and scrolling buttons work fine, just the side buttons not working (and the little app-switcher button, but I understand that might take some special Windows software to recognize or something?).
