AutoHideLeftContainers Issue

I am trying to implement two tool windows within a auto hide left structure.  I patterned what I did after one of your samples.

Here is the XAML from your sample:

<docking:DockSite.AutoHideLeftContainers>

<docking:ToolWindowContainer>

<docking:ToolWindow x:Name="toolboxToolWindow" Title="Toolbox" ImageSource="/Resources/Images/Toolbox16.png">

<TextBlock Margin="3" Text="Place toolbox items here." />

</docking:ToolWindow>

</docking:ToolWindowContainer>

<docking:ToolWindowContainer>

<docking:ToolWindow x:Name="toolWindowDockingToolWindow" Title="Tool Window Docking" ImageSource="/Resources/Images/Properties16.png">

<Border Background="{DynamicResource {x:Static SystemColors.WindowBrushKey}}">

<ScrollViewer VerticalScrollBarVisibility="Auto">

<StackPanel Margin="7">

<TextBlock Text="Tool Windows (Open in bold):" TextWrapping="Wrap" />

<ListBox x:Name="toolWindowsListBox" Margin="0,3,0,0" Height="150" ItemsSource="{Binding ElementName=dockSite, Path=ToolWindows}" SelectedIndex="0">

<ListBox.ItemTemplate>

<DataTemplate DataType="docking:ToolWindow">

<TextBlock x:Name="title" Text="{Binding Title}" />

<DataTemplate.Triggers>

<DataTrigger Binding="{Binding IsOpen}" Value="True">

<Setter TargetName="title" Property="FontWeight" Value="Bold" />

</DataTrigger>

</DataTemplate.Triggers>

</DataTemplate>

</ListBox.ItemTemplate>

</ListBox>

<TextBlock Margin="0,7,0,0" Text="Actions affect selected tool window in list above:" TextWrapping="Wrap" />

<WrapPanel Margin="0,3,0,0">

<Button Content="Activate" Command="docking:DockingCommands.ActivateWindow"

CommandTarget="{Binding ElementName=toolWindowsListBox, Path=SelectedItem}" />

<Button Content="Open" Command="docking:DockingCommands.OpenWindow"

CommandTarget="{Binding ElementName=toolWindowsListBox, Path=SelectedItem}" />

<Button Content="Close" Command="docking:DockingCommands.CloseWindow"

CommandTarget="{Binding ElementName=toolWindowsListBox, Path=SelectedItem}" />

<Button Content="Destroy" Click="OnDestroyToolWindowButtonClick" />

</WrapPanel>

<WrapPanel Margin="0,3,0,0">

<TextBlock Text="Direction " VerticalAlignment="Center" />

<ComboBox x:Name="programmaticDockDirectionComboBox" SelectedIndex="3"

ItemsSource="{Binding Source={StaticResource DirectionObjectDataProvider}}" />

<Button Content="Dock to DockSite" Click="OnProgrammaticDockToDockSiteButtonClick" />

<Button Content="Dock to Solution Explorer" Click="OnProgrammaticDockToSolutionExplorerButtonClick" />

</WrapPanel>

<GroupBox Header="Float" Margin="0,7,0,0" Padding="3,2,3,0">

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

<RowDefinition Height="3" />

<RowDefinition Height="Auto" />

<RowDefinition Height="3" />

<RowDefinition Height="Auto" />

<RowDefinition Height="3" />

<RowDefinition Height="Auto" />

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="Auto" />

<ColumnDefinition Width="3" />

<ColumnDefinition Width="*" />

</Grid.ColumnDefinitions>

<TextBlock Text="Position:" HorizontalAlignment="Right" VerticalAlignment="Center" />

<editors:PointEditBox x:Name="floatPositionEditBox" Grid.Column="2"

CheckBoxVisibility="Visible" InitialValue="100,100" />

<TextBlock Text="Size:" Grid.Row="2" HorizontalAlignment="Right"

VerticalAlignment="Center" />

<editors:SizeEditBox x:Name="floatSizeEditBox" Grid.Row="2" Grid.Column="2"

CheckBoxVisibility="Visible" InitialValue="200, 300" />

<TextBlock Text="Behavior:" Grid.Row="4" HorizontalAlignment="Right"

VerticalAlignment="Center" />

<ComboBox x:Name="floatSizingBehaviorComboBox" Grid.Row="4" Grid.Column="2"

SelectedIndex="0"

ItemsSource="{Binding Source={StaticResource FloatSizingBehaviorObjectDataProvider}}" />

<Button Grid.Row="6" Grid.ColumnSpan="3" HorizontalAlignment="Right"

Content="Float" Click="OnFloatToolWindowButtonClick" />

</Grid>

</GroupBox>

</StackPanel>

</ScrollViewer>

</Border>

</docking:ToolWindow>

</docking:ToolWindowContainer>

</docking:DockSite.AutoHideLeftContainers>

Here is the XAML from my application:

<docking:DockSite.AutoHideLeftContainers>

<docking:ToolWindowContainer x:Name="DataAcquisitionToolWindowContainer" docking:DockSite.ControlSize="750,600">

<docking:ToolWindow x:Name="InstrumentControlToolWindow" Background="{DynamicResource FixedPanelBackground}"

Title="{x:Static properties:Resources.InstrumentControlTitle}" Style="{DynamicResource ToolWindowStyle}">

<views:InstrumentControlView x:Name="InstrumentControlView"/>

</docking:ToolWindow>

</docking:ToolWindowContainer>

<docking:ToolWindowContainer docking:DockSite.ControlSize="750,600">

<docking:ToolWindow x:Name="LiveDataWindow" Title="{x:Static properties:Resources.LiveData}" Style="{DynamicResource ToolWindowStyle}">

<views:LiveDataView x:Name="LiveDataView"/>

</docking:ToolWindow>

</docking:ToolWindowContainer>

</docking:DockSite.AutoHideLeftContainers>

As you can see, both have two tool windows within the container.  When I start the application, both tool windows show up as collapsed on the left side, as they should according to my understanding.  The problem I am having is as follows:  If I "unhide" and pin both windows and then unpin them, the one on the right gets "hidden" on the right side instead of on the left side.  Is there anything special I have to do to get this window to "rehide" properly back on the left side?

Thanks.
