Object Error in OnPaint

When I click on a certain column in a Databound grid I get an "Object reference not set to an instance of an object." error in the OnPaint event. I have no code in this event. Any clue on why this is happening?

Are you using multiple threads? If so, are you protecting calls into the grid using grid.InvokeRequired checks? Threading problems can manifest themselves in errore of this nature. What kind of column is the problem column? Can you post a sample project showing the problem? Or, can you post a call stack from when the exception is thrown?

Here is the call stack. I''ll work on getting an sample together.
