Additional Notes

This version allows for scrolling of background windows as long as part of them is showing and your mouse cursor is on it. Also, it allows scrolling in older programs like WordPerfect 6.1. I'm using this driver right now with my brand new (as of Dec. 9, 2005) and totally updated copy of XP Home with SP2. This Kensington driver and program is vastly superior to Microsoft's Intellimouse, any version.
