I struggled with this issue a while back. If my memory serves me right, it has to do with the fact that the grid has focus and it's trying to refresh itself, therefore, read thru all the records at the same time you're trying to update a record. The solution is to move focus off the grid, then do your REPLACE, then move focus back to the grid.

Hope this helps,
