Hi. I'll try to explain with my english :)
Here is the C# script that will show this issue:

using System;

using System.Windows.Forms;

using Sony.Vegas;



public class EntryPoint

{    

	public void FromVegas(Vegas vegas)

	{

		// Create tracks

		vegas.NewProject(false, false);	

		vegas.Project.Tracks.Clear();

		VideoTrack trackA = vegas.Project.AddVideoTrack();

		trackA.Name = "Track A";

		VideoTrack trackB = vegas.Project.AddVideoTrack();

		trackB.Name = "Track B";



		// Select trackA

		trackA.Selected = true;



		vegas.UpdateUI();



		MessageBox.Show("Track A is selected. Now close this message & run Tools - Video - Track Motion" + Environment.NewLine + "Track Motion Window for track B will be opened");

	}

}

Track A is selected but all track commands which I run from menu or shortcuts operate with Track B. Is it normal? I see that Track B is "focused" (it has small blinking dot) but I can not set the focus to Track A via script. I want to select track as I do it manually with mouse (property Focused is missing)
The same problem with events: If I select some events with mouse and then a script selects another, I'll face with the same issue: all events menu commands operate with another events.
