I have a Logitech M-BT85 optical USB mouse (with wheel). It works fine with FC4 [Linux version 2.6.12-1.1447_FC4] most of the time. See lsusb output below FWIW. Occasionally, when I'm mousing around doing nothing special, the cursor takes off like crazy across the screen and lands somewhere at the edge. Really annoying! My mouse preferences are all set to middle values. Have I got a bad mouse, or do we have USB / driver problems? Is it a known problem? Should I declare a bug? Thanks for any clues. -- martin.ewing@xxxxxxxxx http://blog.aa6e.net ---------------------- lsusb: Bus 003 Device 003: ID 046d:c03f Logitech, Inc.
