I experienced the same thing -- it does not work properly in its current form (I expect you're talking about the AutoCompleteBox that comes with the February 2010 release of WPFToolkit).

I created a subclass:

public class AutoCompleteFocusableBox : AutoCompleteBox
{
    public override void OnApplyTemplate()
    {
        base.OnApplyTemplate();
        var textbox = Template.FindName("Text", this) as TextBox;
        if(textbox != null) textbox.Focus();
    }
}

This sets focus to the actual TextBox (called "Text") that is part of the default ControlTemplate.
