There are three ways to configure TRACE32 to start as a hidden instance by adding different SCREEN= options in the configuration file (e.g. config.t32). Choose one of the configuration options:

1. The main window of TRACE32 remains hidden. However, dialogs and other window of TRACE32 can still be opened. This is useful, for example, if an error occurs during a regression test.
   
   SCREEN=
   INVISIBLE
   
   
2. The main window of TRACE32 and all other dialogs and windows of TRACE32 remain hidden - even if an error occurs.
   
   SCREEN=OFF
   
   
3. The main window of TRACE32 is added to the toolbar of the host computer. It can be fully displayed in case of an error.
