To fix MySQL Administrator error ”Could not fetch schema table status”, simply disable McAfee and your problem should be solved 
DataGridView has column sorting enabled by default. It’s usually a good thing but in some rare cases it can be a problem and should be disabled. To disable it, add a ColumnAdded event:
this.dataGridView1.ColumnAdded += new System.Windows.Forms.DataGridViewColumnEventHandler( this.dataGridView1_ColumnAdded);
and add a function to disable the sorter on the column which is being added like this:
private void dataGridView1_ColumnAdded(object sender, DataGridViewColumnEventArgs e)
{
dataGridView1.Columns[e.Column.DisplayIndex].SortMode = DataGridViewColumnSortMode.NotSortable;
}
