Touchpad scroll bars stop working after installing MS Bluetooth mouse

After installing a MS Intellimouse for Bluetooth mouse and driver on my 9300, the mouse works fine, but my scroll bars on the touchpad have stopped working. The touchpad still works, but I have to mouse over to the screen elevator bars and click to scroll - what a pain. When I'm travelling, I don't usually take the mouse with me, and I really miss those scroll areas. Any ideas? My MS intellipoint driver version is 5.20.413.0 dated 6/3/04. There don't seem to be any settings related to the touchpad anymore, and I can't find any other specific properties screens for the touchpad. I seems like the mouse driver install uninstalled the original drivers. Is there anyway to have both pointing devices running their own drivers?
