On a Microsoft Wireless Mouse 5000 I just bought, the right side button (for next page) is far softer than the left side button (for last page). Specifically, the right side button travels much farther than the left side button in order to click, making it unusually difficult to push. Is this normal? or should the mouse be returned and replaced?
Edit: The mouse button responds normally, and registers every time the button is fully depressed, but I'm not sure whether this would fail over time, and it is more difficult to press than it should be. In any case, there is a three-year warranty on the mouse.
