Hi Bruno.
I have more info about.
If you can, try this:
1 - place a TDBAdvGrid and a TDBAdvNavigator on a form
2 - set the same datasource
3 - set TDBAdvGrid.FixedCols := 2 (a value > 1 [the standard value])4 - select cell on column 3 (the first column after the FixedCols)
5 - use the button Next on the TDBAdvNavigator until you reach the end of the grid and view the new records after end of the grid
6 - see whats happen on the values in the fixedcols. They don't change
This doesn't happen if you select a cell on column 4 or superior.
I've installed last version of VCL UI.
