I have created sample, where occurs such problem. Sometimes after resizing grid columns or after sometime appear unwanted cells on unexisted columns (See StrangeDraw.zip).
Where can be a problem?

You can only access the grid (or any other Windows Forms control) on the thread that created it. The m_OnUpdate handler is being called from nonUI threads, so you have to recall it on the UI thread that created the grid.
