title: tooltip under mouse cursor - flickering
body: <p>I have set tooltip under mouse cursor, but It's flashing all the time, even If cursor doesn't move. Any ideas on how to prevent tooltip flickering ?</p>
  
  <p>Code:</p>
  
  <pre><code>   Private Sub DataGridView1_MouseHover(sender As Object, e As EventArgs) Handles DataGridView1.MouseHover
  
  
          Dim cur = DataGridView1.HitTest(e.X, e.Y)
  
          If cur.RowIndex &gt;= 0 AndAlso cur.ColumnIndex &gt;= 0 Then
  
              DataGridView1.Cursor = Cursors.Help
  
              ToolTip1.Active = True
              Dim cp = Cursor.Position
              cp.Y += CInt(Cursor.Size.Height * 0.2)
              cp.X += CInt(Cursor.Size.Width * 0.8)
              ToolTip1.Show("Details...", Me, PointToClient(cp))
  
          Else
              DataGridView1.Cursor = Cursors.Default
              ToolTip1.Active = False
          End If
  
      End Sub 
  </code></pre>
