//Workaround for .NET bug: When showing context menu in inactive thread, immediately closes it. Not always, but eg after showing in active.
// In some cases vice versa: when showing in active thread after showing in inactive.
// It happens when the .NET message loop receives any posted message and it is handled by ToolStripManager.ModalMenuFilter nested class.
// If then ModalMenuFilter._lastActiveWindow != GetActiveWindow(), closes menu. But _lastActiveWindow is not updated in inactive thread.
