Hi,

I have these 2 tables. Detail.dbf and proditem.dbf. Relation is set to detail.itemcode -> proditem.itemcode

Detail.dbf
- itemcode
- amount

Proditem.dbf
- itemcode
- itemdesciptions

I have a save, edit, top, previous, next, bottom and undo buttons in my form with grid.
In the grid, column1 is Detail.itemcode, column2 is proditem.itemdescription, column3 is Detail.amount

Why is it that there are times when the record displayed in column2(itemdesciption) suddenly changes descriptions and doesn't match the itemcode in column1 when i try to click edit button and I moved/passes my cursor/arrow pointer over the grid header and then without changing anything, I click the undo button. But when I click the any of the navigation buttons and return to that record again to check, it now displays the correct description. This only happens when i pass my cursor(arrow pointer) over the grid header when editing.

What could I be missing in my form?

Thanks in advance
