scoll wheel setting on a 200 laptop

Hello,
I have a 200 XL with the scoll wheel touchpad and a Microsoft USB
scroll wheel optical mouse. The scoll wheel setting "lines per scroll"
always defaults to 1 after each reboot. I am currently using the
Synaptics touchpad driver. Is there a registry setting I can modify to
make my preferences permanent? I also had this problem with a Solo5300
with the standard touchpad and a scroll wheel USB mouse. Removing the
Synaptics driver and just using the generic microsoft driver fixed the
problem. My guess is that Synaptics drivers aren't designed to keep
track of this setting. Is that my only option again?
Thanks for any help. Please respond to the group.
