Strange Multiple Displays Problem

[WilsonF]

With Vista business, my T60p (2623-DDU) loses the setting about which side of my laptop display the secondary display should occupy whenever I resume from standby or hibernation. That is, if I set Monitor 2 to be on the left side of Monitor 1 using Personalize> Display Setings, when I resume from hibernation or standby, Monitor 2 is back on the right side of Monitor 1.

XP remembers where Monitor 2 belongs.

Does anyone know how to fix this so Vista remembers where the secondary display belongs?
