IBO 4.5B, Delphi 7

I have been trying to enable the IndicateSort property on the columns
in a IB_Ledger component. The property was not saved in the IB_Ledger
Editor and always reverted to unchecked.

I noticed in the IB_LedgerEditor.pas that the cbIndicateSort component
has no OnClick event assigned even though one exists in the code.

Is there some reason to disable this in a ledger?

Is there some other way to get an OnDrawTitle or similar so I can
indicate through color/font/bitmap which column is sorted?

TIA
