Sometimes when I activate a window with keyboard commands, like Alt-Tab or Win, the mouse cursor will jump to the middle of the newly activated window. I have searched my mouse control panel and TweakUI for options that might activate this without any success.

Does anyone know how I can make this stop? It's driving me nuts.

I have an IBM/Lenovo 800dpi ScrollPoint Optical with the Lenovo MouseSuite v5.03.8 drivers. I have X-Mouse activation (but not raise) enabled via TweakUI. It's an IBM laptop that also has a trackpoint and a touchpad, with the UltraNav drivers loaded.
