This is a basic UI issue.
When I scroll the Laps and Splits grid to select a lap that is not visible in the initial page display, the row for that lap is highlighted and the grid scrolls to the top.
As a result, the Lap I've selected is no longer visible and I have to scroll again to select the next lap.
Please stop the grid from redrawing or, if that's not possible, re-select the selected Lap after the grid redraws.
