LongListSelector not scrolling

Question

I am having trouble getting my long list selector to work properly. When the list is taller than the screen, the long list selector stays static and I am unable to scroll to see all of the items.

Any thoughts?

<phone:PivotItem Header="{Binding Path=LocalizedResources.ApplicationsHeader, Source={StaticResource LocalizedStrings}}" x:Name="applicationsPivotItem">
    <Grid x:Name="applications" Grid.Row="1">
        <phone:LongListSelector x:Name="MainLongListSelector" ItemsSource="{Binding Items}" SelectionChanged="MainLongListSelector_SelectionChanged">
            <phone:LongListSelector.ItemTemplate>
                <DataTemplate>
                    <StackPanel>
                        <TextBlock Text="{Binding LineOne}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                        <TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
                    </StackPanel>
                </DataTemplate>
            </phone:LongListSelector.ItemTemplate>
        </phone:LongListSelector>
    </Grid>
</phone:PivotItem>

Fix the Height of the Grid

<Grid x:Name="applications" Grid.Row="1" Height="400">
...long list code...
</Grid>
