yes, works well now, thanks! I have noted that VBoxSvc.exe does not auto quit after all vms and console gui are closed. It used to quit automatically when no vbox instance running. Not sure if this is a bug, perhaps some references are not released properly. (this is not to do with snapshots)

Please check the next sync. Deleting snapshot only failed if the snapshot was taken in the same session (i.e. without a VBoxSVC restart) because VBoxSVC failed to update medium backreferences correctly after a snapshot was taken.
