In this case, reproduction steps are not clear for us.
EO.WebBrowser v15.2.10.0 throws NullReferenceException after triggering CallbackOnCollectedDelegate MDA.
Managed Debugging Assistant 'CallbackOnCollectedDelegate' has detected a problem in 'application.exe'.
Additional information: A callback was made on a garbage collected delegate of type 'EO.WebBrowser!EO.Internal.am3+a::Invoke'. This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called.
NullReferenceException:
EO.Internal.nl.a(EO.Internal.uw, EO.Internal.nl)
EO.Internal.cs+<>c__DisplayClass4.<DispatchMessage>b__0(System.Object)
System.Threading.QueueUserWorkItemCallback.WaitCallback_Context(System.Object)
System.Threading.ExecutionContext.RunInternal(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem()
System.Threading.ThreadPoolWorkQueue.Dispatch()
System.Threading._ThreadPoolWaitCallback.PerformWaitCallback()

Hi, We are aware of this problem but we have not been able to reproduce it. Can you try to isolate the problem into a test app and send us the test app? See here for instructions on sending test app to us: http://www.essentialobjects.com/forum/test_project.aspxThanks!
