I tested the wireless USB mouse on KDE and it works on every app I've tested. There are literally a hundred plus apps so it will take me some time to test each one but I can see the mouse on any part of screen and app and it even works while screen keyboard is on screen. The best part is that I have right click menu ability. Scroll wheel and left and right click works. Wireless USB Mouse with bt keyboard and full office apps and real computer apps makes my N800 the smallest full feature computer out there. Great job JoLouis and Benson. Sweeeet! Dan
