wpf 连续弹出模态对话框的问题
主窗口弹出模态对话框(a)后,再从子模态对话框(a)弹出模态对话框(b)
用鼠标点击父窗口是正常的,但是从任务栏选中窗口(a),居然可以激活窗口(a)
按下空格键,可以继续从窗口(a)中弹出模态对话框(c)

有什么好的解决方案?

代码如下

xaml
<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="12,12,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="141,12,0,0" Name="button2" VerticalAlignment="Top" Width="75" Click="button2_Click" />
    </Grid>
