Why does nothing happen when I use Actions>Revert to Snapshot? When I load a VM with a number of Snapshots already present and I then want to go back to a previous Snapshot I seem to have 2 options: 1. I can select a particular Snapshot from the Control Panel and click on the Delete button 2. I can go to the main program toolbar and under the Actions menu, select the Revert to Snapshot option. However nothing appear to happen? I notice that this option is missing from the right-click pop-up menu on a Snapshot, does this mean the option is not valid?
