I have a checkbox in a grid with this code in interactivechange method:

TRY
IF THIS.VALUE = .T. AND InventoryByRequisition.TaxCredit = .T.
REPLACE InventoryByRequisition.TaxCredit WITH .F.
ENDIF
CATCH TO oEx
oEx = NULL
ENDTRY

When I check / uncheck by using the mouse or the spacebar everything works fine, but pressing the Enter key clears the grid and I haven't found a way to to debug or recover from this behavior.

There is no custom code in the when or valid section of the checkbox.

TIA
