Mark,
Thanks! That seems to have worked, but now my question is why? I have used this grid class on many forms and never had a problem. This is the first time I put the grid on a form class. Is that where my problem stems from? Is it a bad practice to put objects, such as grids, onto form classes?

I seem to have noticed some other strange behavior, such as Column background properties not being inherited from the class to the Form.

Thanks again for your help.
