The left mouse button on my microsoft optical mouse 2.0 is not so responsive. Some events do respond to it, but many do not. I plugged in another MS USB mouse at the same time and use the left mouse button on that without any problems. Other actions of the first mouse are fine - scrolling and movement respond perfectly and accurately. And the mouse click event does work many times, or after many clicks - just not all the time.
What could be the problem?
I am using intellipoint 220.127.116.11 as the driver for both mice on a windows XP Pro computer
