>You just need to override your application's Factory CreateSecuritySetupForm() method like this...

public class Factory : OakLeaf.MM.Main.Windows.Forms.mmFactoryDesktop
{
	public override OakLeaf.MM.Main.Windows.Forms.mmSecuritySetupForm CreateSecuritySetupForm
		(OakLeaf.MM.Main.Windows.Forms.ImmUISecurity secureControl)
	{
		return new SecuritySetupForm(secureControl);
	}
}

Okay, I got it working fine.

btw, I had to change the constructor in my form to take the same ImmUISecurity parameter as mmSecuritySetupForm, and then call the constructor in the base class, like this:

public SecuritySetupForm(ImmUISecurity secureControl) : base(secureControl)
{
	this.grpUsers.Visible = false;
	this.lstUsers.Visible = false;
	...
}

(I don't call InitializeComponent in my constructor.)

Thanks.
