>>I am using version 6 SP5. My grid is populated by SPT cursor from an AS400 Logical file. There are no filters. I sure have a problem with errors that are not consistant. I set here trying to reproduce the problem, but nothing seems to trigger it, it just happens then quits happening.

I have seen this as well, and I believe it has something to with setting a column's .SPARSE = .T. IMO it has nothing to do with SPT or views.
