Delphi 7, IBO 4.3

I have a form to edit customer information. Above are some edit
controls and below is a IB_Ledger control set to read only to
prevent any editing directly in the grid.

When I open the form, I cannot edit the first row until I change
rows. After the first change of row, I can edit everything just
fine.

Is there some setting I am missing to allow editing when the form
opens?

TIA

Rick
