windows - Click lost on focusing form

Question: Is there a way to always let a click, that brings a form in to focus, through an have effect on the form?

Background: With my (C# win form) application out of focus I can hover the form and get shades and borders indicating where my mouse is.

Clicking for example a menu entry (File) the form gets focus but the file menu does not get click. This takes an additional click.

For an ordinary button on the form only one click is required.

This can be fixed by setting focus before the click occurs. Se code:

class ToolStripEx : System.Windows.Forms.ToolStrip
{
    protected override void WndProc(ref Message m)
    {
        // WM_MOUSEACTIVATE = 0x21
        if (m.Msg == 0x21 && this.CanFocus && !this.Focused)
        {
            this.Focus();
        }
        base.WndProc(ref m);
    }
}

This approach also works on MenuStrip
