..this doe NOT WORK It does allow the semblance that they drivers are installing but upon rebooting the driver remains the standard mouse driver, the intellipoint services are NOT running and the diagnostic utility states that intellipoint is NOT installed. Any one else? that seemed like a great Idea at least it got us past the message that these drivers were not for this OS. I find it really hard to belive that these drivers work under XP but NOT under 2003..its all a big conspiracy..this is the one thing keeping unhappy about 2003.
