Sorry, I should have mentioned that. I do.
If I simply use a native table for the recordsource, it works as expected. It is when I use a cusor, that changes from customer to customer, that seems to cause the problem to arise. The check box is gone from the grid and all that is presented is the "T" or "F". Also if you attempt to change the value, VFP says this control is read only even though I set the the read only property to false.
Thanks.
