Add a check in the Navigator window under Scripting to allow Enable or Disable the Startup or Shutdown scripting to run.
During debugging, I frequently need to disable the workspace to run the Startup Python scripting. either I Cut and paste to Notepad, or I have to o comment out all script lines just for the sake of testing.
i can add a private parameter Type Choice "Debug" with values Yes/No, but I guess it'll be more handy if it is set by default in the Navigator window for any workspace.
