Development Server compilation and Debuging ...

hmm, I hate any errors but this is unusual…
I have finally found where it is setting it but not how to change it.

In SSessionLauncherPreviewPage.cpp (Engine Source) we have the following:

• SVerticalBox::Slot()
  .AutoHeight()
  .Padding(0.0f, 8.0f, 0.0f, 0.0f)

    								SNew(SHorizontalBox)
  
    								+ SHorizontalBox::Slot()
    									.AutoWidth()
    									
    										SNew(STextBlock)
    											.Text(LOCTEXT("CommandLineLabel", "Command Line:"))
    									]
  
    								+ SHorizontalBox::Slot()
    									.FillWidth(1.0f)
    									.HAlign(HAlign_Right)
    									.Padding(8.0f, 0.0f, 0.0f, 0.0f)
    									
    										// command line
    										SNew(STextBlock)
    											.Text(this, &SSessionLauncherPreviewPage::HandleCommandLineTextBlockText)
    									]
    							]
  

This is part of the // launch section
But in the Editor I am unable to locate that Menu item anywhere in the editor settings so far… been looking hard.

(edit)
Argh… Its a default setting somewhere, once I started a Full Packaging of the TestFPP the error returned.
I suspect I have run the Launcher app seperate from the editor to get at it.
