I'm trying to troubleshoot a problem with the trackpad scroll speed using Mavericks on a MacBook Pro.

Setting the trackpad speed in System Prefs -> Accessibility ->Mouse & Trackpad -> Trackpad Options sets the desired scroll speed, however, it doesn't persist through a restart, logout, or user change - sleep is OK though.

Tried repairing permissions, and deleting the various pref files - any other ideas?
