Thank you for your reply, Senna. The current record number (recno()) does not change when I use up/down arrow on the scroll bar. However, it changes when I move thumb up and down, though active row number does not change. I also feel confused by FoxPro Grid's activity when I scroll down to last record in the grid on a Master/Detail form.

My problem is that I have code to verify the data in AfterRowColChanged. The unexpected current record changes triggers unexpected execution.
