I replaced the Toshiba BT stack with the Widcomm one on my ST5021. The Widcomm stack does interfere with the power management features of the ST5021 in not allowing the unit to enter Standby - message something like "BT driver is preventing Windows from entering Standby. Check for updated driver....."
I reverted to the Toshiba stack because it provided the same level of functionality I needed without the error messages.
