Just want to ensure that we are on the same page and I'm not making any false assumptions.
Here is my experience / finding
When there are freezeCols > 0 and:
1. row is selected via click on number cell, any cell in the grid is not focused and row is not copied.
2. row is selected via mousedown on number cell and mouse is dragged over to a cell in grid before mouseup, that cell is focused and row copy works fine.
Please confirm or let me know the details if you have different experience.
