Too obvious, I suppose, but my Logitech wireless (but with a ball) takes two triple-A batteries. Open the control panel. Mine has a battery icon. If the top is shaded whatever color, probably red, the batteries are shot. If the bottom half of the icon shows green, move on to Part 2.
Part 2: I just downloaded Netscape 6.1 because iCab won't work at Penguin Books, and Netscape played hell with the mouse. The wheel stopped working — sometimes. After putting new batteries in the mouse, which didn't fix it, I quit Netscape and used iCab to check out Logitech and discovered an updated driver, 4.1 or 4.01 or something. I had 3.5. Their 4.0 driver had problems, so they fixed it and released 4.whatever and now it even works with Netscape. If none of that fixes it, move on to Part 3.
Part 3: If you're running Mouseware 3.5, make sure that stupid WebWheel is in the System Folder. If it isn't, nothing works. It appears to be gone with 4.whatever, thank the gods. If this doesn't fix it, move on to Part 4.
Part 4: Blow up the Logitech mouse real good.
