In a system with search button to fill the grid try it:
1. Search and fill the grid in order to fill until the scroll apear.
2.Now, scrow down until the last line and cli in the last line.
3.Now research again in orde to select only 3 or 4 lines. The number of lines that you have sure that you dont need the scrool anymore.
4.Take a look. The scrool still there and the grid dont show the first record.
If someone know how do something about that let me know.
