What if a setting is changed, how to make sure it is set the same way the next time WinMLS is started?

All WinMLS settings are saved to a temporary setup file that can be loaded when WinMLS is started (set this from Setup->Options…). Then your settings will remain the same as when you closed WinMLS. But if a new setup is loaded (using Setup->Load...), these settings are lost. Therefore we recommend that you save the settings using Setup->Store...).
