hi there

i have a VGN-T150P. 

now, my touchpad’s acting funny, and i’ve followed the suggestions from:
http://www.siliconpopculture.com/sonytr/viewtopic.php?t=4893&highlight=touchpad

when i go into Sony Notebook Setup and look into Device, i see Pointing Device.  when i select that, Alps Wide Pointing-device for VAIO comes up as the Mouse Properties. 

there’re four tabs here: Buttons, Pointers, Pointer Options, and Hardware.  But there’s no Advanced Features tab where i can look into Touchpad’s settings in my other laptop. 

am i missing the touch pad driver here? 
if so, can i D/L just that driver from somewhere, or do i have to D/L the whole “Utilities”, “Control Device Driver Utility”, and “Shared Library Utility”? 

thanks in advance.
