We use the following process when using our home computer:
1. Start or Wake the computer
2. Login - either as admin, power user or user
However many times Standby simply halts and the 'Your Computer is going to Standby' dialog remains frozen on the screen.
If I (admin) login, do something, then logout, it appears to Standby ok.
If other users (power users and users) login then logout, it generally does NOT go to Standby.
If we wake computer, do NOT login, and Standby again, always freezes.
