Description of Problem:
In MS's runtime this code work fine, in mono linux behavior unexpected!
Steps to reproduce the problem:
1. Generate and compile the code!
-- Program.cs
using System;
using System.Collections.Generic;

{
/// <summary>
/// The main entry point for the application.

{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new frmDataGridProblem());
}
}
}

2. Execute the program in mono linux, select first row "Memo 0", after press
down arrow key, bookmark select next row, press again down arrow key and again
until select last row. When the last row is selected, the rows 0,1,2,3,4 are
hided.
Actual Results:
The rows are being hided from DataGridView
Expected Results:
No hide rows.
How often does this happen?
Ever, All!
