Hi there, I've recently imaged about 8 iMacs using a FireWire drive. The hardware is identical on each. The problem I am getting is that when a student logs into the machine (with a managed account), they come to log out and the apple menu disappears but the dock remains and log out does not happen. I either have to switch off using the button/pulling the plug, or by putting the computer into standby, then switching user to log in as someone else (either standard account or admin) and I am then able to log out/restart/shutdown. The problem never happens when logged in as a standard user or admin... This logout problem happens on each of the machines but not always. Sometimes it will log out of the student account just fine, but other times it won't. It's proving to be very annoying. I did search for this problem and uncovered this page but that has so far proven unsuccessful as the problem still occurs. Does anyone have any other ideas or suggestions please?
