Delphi - Error con BD Acces al recorrer dbgrid

Tengo un problema con mi aplicacion, uso una Base de Datos de Acces y ADO con Delphi 5.
El problema es que corro el programa y funciona, pero solo en ocaciones al recorrer todos los campos de una tabla que se muestran en un dbgrid aparece el error:

'Either BOF or EOF is True, or the current record has been deleted.
Requested operation requires a current record'

Que es lo que esta mal.. y por que nadamas cuando recorro todo el dbgrid? y solo deves en cuando. Espero me contesten gracias.

Es un bug de ADO, Necesitas descargarte un parche, concretamente el ADOExpress UPDATE PACK 2.

ISSUES RESOLVED IN THIS UPDATE

This update corrects a known issue which affects certain ADOExpress applications when running against MDAC 2.6. Most commonly, the following error is generated when closing an empty dataset:
"Either EOF or BOF is True, or the current record has been deleted. Requested operation requires a current record". The same error may also occur when canceling an edit operation. Affected applications should be recompiled after the update is installed.
