title: Not enough quota is available to process this command -WPF
body: <p>I am working on a WPF application. I have implemented error handling and implemented   error mail sending feature for this application. So admin will get the error message if any error happened  in the application.
  My issue is we are always getting a following error message.</p>
  
  <blockquote>
    <p>Error : <strong>Not enough quota is available to process this command</strong></p>
    
    <p>MS.Win32.UnsafeNativeMethods.PostMessage(HandleRef hwnd, WindowMessage msg, IntPtr wparam, IntPtr lparam) at System.Windows.Interop.HwndTarget.UpdateWindowSettings(Boolean enableRenderTarget, Nullable`1 channelSet) at System.Windows.Interop.HwndTarget.UpdateWindowPos(IntPtr lParam) at System.Windows.Interop.HwndTarget.HandleMessage(WindowMessage msg, IntPtr wparam, IntPtr lparam) at System.Windows.Interop.HwndSource.HwndTargetFilterMessage(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean&amp; handled) at MS.Win32.HwndWrapper.WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean&amp; handled) at MS.Win32.HwndSubclass.DispatcherCallbackOperation(Object o) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) at MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler)</p>

  <p>We have used <strong>MVVM light toolkit messengers, task</strong> etc for this application.
  Also I have a data grid in the application.</p>
  
  <p>How we trace this error?  Anyone knows the reason of this “Not enough quota is available error”?
  Any help would be appreciable.
  Thanks in Advance.</p>
