When I set the Window background to transparent, the bars are now black but still not grabbable. Not sure how to remove the Windows Chrome? Here's the XAML I'm using:
<GridDockPanel.Dock="Bottom"><Grid.RowDefinitions><RowDefinitionHeight="50*"x:Name="GTop"/><RowDefinitionHeight="4"/><RowDefinitionHeight="50*"x:Name="GBottom"/><RowDefinitionHeight="Auto"/></Grid.RowDefinitions><Grid.ColumnDefinitions><ColumnDefinitionWidth="50*"x:Name="GLeft"/><ColumnDefinitionWidth="4"/><ColumnDefinitionWidth="50*"x:Name="GRight"/></Grid.ColumnDefinitions><Classes:SplitterBackground="DarkGreen"Grid.ColumnSpan="3"Grid.Row="1"Direction="HORIZONTAL"PreviousRow="{Binding ElementName=GTop}"NextRow="{Binding ElementName=GBottom}"/><Classes:SplitterBackground="DarkBlue"Grid.RowSpan="4"Grid.Column="1"Direction="VERTICAL"PreviousColumn="{Binding ElementName=GLeft}"NextColumn="{Binding ElementName=GRight}"/><Classes:SplitterBackground="Red"Grid.Column="1"Grid.Row="1"Direction="CROSS"PreviousRow="{Binding ElementName=GTop}"NextRow="{Binding ElementName=GBottom}"PreviousColumn="{Binding ElementName=GLeft}"NextColumn="{Binding ElementName=GRight}"/><StackPanelGrid.Row="0"Grid.Column="0"Background="Red"/><StackPanelGrid.Row="0"Grid.Column="2"Background="Blue"/><StackPanelGrid.Row="2"Grid.Column="0"Background="Tan"/><StackPanelGrid.Row="2"Grid.Column="2"Background="Brown"/><StatusBarGrid.Row="3"Grid.Column="0"Visibility="{Binding Source={StaticResource MySettings},Path=ShowStatusBars,Converter={StaticResource boolToVisibleConverter},Mode=TwoWay}"><StatusBarItem><TextBlockName="StatusBarLeftText"Text="{Binding Source={StaticResource MySettings},Path=LeftDir}"/></StatusBarItem></StatusBar><StatusBarGrid.Row="3"Grid.Column="2"Visibility="{Binding Source={StaticResource MySettings},Path=ShowStatusBars,Converter={StaticResource boolToVisibleConverter},Mode=TwoWay}"><StatusBarItem><TextBlockName="StatusBarRightText"Text="{Binding Source={StaticResource MySettings},Path=RightDir}"/></StatusBarItem></StatusBar></Grid>
