Model: Serial Scrolling Mouse V5.10
Operating System: Windows 98 (Note: might work with other versions of this os.)
I sometimes have an install problem w/these drivers where the driver keeps recognizing the mouse, confirming install, offering to restart, and then upon restart re-recognizing the mouse w/o being installed (but offering another restart). Once they are installed correctly everything works fine though (seems to need to be wiped clean from system first before reinstalling)
Yup, the Kensiko website is down for the count, no help there.
