We have Engineer's Toolset V10 10.6.0.84 and I have a problem with the Workspace Studio losing configuration. Whenever we need to close the app or reboot the server, the WS comes back up with default devices and no credentials. I have to re-add all of our devices and associate them with the proper credential sets. The devices and credentials are still accessible via the other tools, so it's not losing all setup info, just in the Workspace Studio. Do I have to export devices to a file to get it to remember them, or is there a save button I haven't found yet?
