I found a bug where when a folder in the root (and maybe elsewhere ?) has download password on it. If someone without access tries to tick the archive and download, it will actually archive the rest of the folders in that folder (in my example other folders in root) and try to send them. It should probably do nothing or come up with an error message saying you don't have access to this folder. Perhaps there shouldn't even be a tick option for those folders you don't have download access to.
Also, could we have log off option as well ? I logged in and wanted to view the server as another persona and couldn't log off.
