Lorne,
Are you sure buffering is off? If so, then TableUpdate() should have given you an error message as it requires buffering.

Use CursorGetProp() to find out the buffering level during your scatter/gather. If buffering is set to row or table buffering that would cause the problems you were seeing.

>IF !EOF()
