I just received an MX3200 keyboard/MX600 mouse combination and installed it on my Vista 32 machine. (I had previously used a no-name wireless combo that ultimately wore out.) I installed the latest Logitech drivers, made sure batteries were fresh, that it was properly connected. However, the mouse is not behaving properly. It acts like a regular roller ball mouse does when the ball is jammed or on the wrong surface--the cursor doesn't track the mouse motions. I have to repeatedly swipe the mouse on the pad to just get it to move a little. In fact, I had to turn my pad over (i have a stiff pad designed for laser/optical mice) to get even lousy responsiveness. I've tried the mouse on soft pads, on the table, on a piece of white paper, to no avail. I made sure the BIOS enabled USB mice. I"ve checked control panel settings, the logitech utility, but nothing there improves the situation. Any advice?

(I used my wired mouse to create this note).
