No idea how this could happen. The exception shows moving mouse over the design area (i.e. not resizing) and there is no content (missing the top design view component). There is no relevant preceding exception that would indicate some failure of creating the design view.

Do you know the steps how to reproduce it? Can you provide a sample test form on which this could be demonstrated? Thanks
