title: Will any IE security setting prevent access to WebBrowser's ObjectForScripting?
body: <p>I have an application that sets a <code>WebBrowser</code>'s <code>ObjectForScripting</code> property to a custom object so that the user can access it from javascript code using <code>window.external</code>. It have always worked fine but now one of my customers seems unable to access it.</p>
  
  <p>I cannot be 100% sure what the problem is because I'd have to access his computer and I don't want to bug him that much since he's a customer and seems like he found a workaround to what he was trying to do. But it seems to me like he cannot access the object at <code>window.external</code>.</p>
  
  <p>Other than unchecking <code>Active Scripting</code> (which doesn't actually prevents access to <code>window.external</code>), do you know any security setting that will prevent access to the object at <code>window.external</code>?</p>
