I have run into a problem on some stations, it keeps
returning the following error (upon exit):

------------------------------------------------------

System.NullReferenceException: Object reference not set
to an instance of an object.
at System.Windows.Forms.RichTextBox.OnHandleDestroyed
(EventArgs e)
at System.Windows.Forms.Control.WmDestroy(Message& m)
at System.Windows.Forms.Control.WndProc(Message& m)
at System.Windows.Forms.TextBoxBase.WndProc(Message& m)
at System.Windows.Forms.RichTextBox.WndProc(Message& m)
at System.Windows.Forms.ControlNativeWindow.OnMessage
(Message& m)
at System.Windows.Forms.ControlNativeWindow.WndProc
(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr
hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
 
Are those stations running the same version of .net framework?
If the code runs on some stations but not others, I suspect some dll must
lacking or is a different version.
