Query: NOT compatible with Windows ME!!!

Included software - IntelliPoint 5.0 - is not compatible with Windows ME. IntelliPoint 4.12 from Microsoft web site IS compatilbe with ME but it's not written for Wireless IntelliMouse Explorer 2.0 hardware - it was written for v1.0. Microsoft, get your act together - how hard can a mouse driver be? The way it's set up in my system now - IntelliPoint 4.12 with this IntelliMouse Explorer 2.0 - is not acceptable - first, no side tilt is recognized with old driver, second, PS/2 port connection makes the mouse jump around sideways, no problem in USB connection but still it moves sideways somewhat slower than up and down. I just can't believe MS is selling this mouse without older Windows support. What a shame.
