Font difference between XP and Vista in wpf app

[ausadmin]

We have a wpf app developed under windows XP SP2. When this app runs under Vista, the text gets clipped in many places - it is as though a different font is used which is slightly larger. I have seen this with both Tahoma and Arial. I could go through and add padding or miniumum height to solve the, but it seems as though that should not be necessary (and may lead to other problems). Has anyone else experienced this? Can anyone provide some advice or pointers? A sample style is as follows:

<Style x:Key="Heading3" TargetType="{x:Type TextBlock}">
<Setter Property="FontWeight" Value="Bold"/>
<Setter Property="Foreground" Value="{DynamicResource textDimmedForegroundBrush}" />
<Setter Property="HorizontalAlignment" Value="Left" />
<Setter Property="FontFamily" Value="Arial"/>
</Style>

Thanks for any help, Tim

I've had this happen, it's a real PITA. i suspect you can get around it by making sure you set the font size explicitly, but even then, I think the best thing to do is to make sure you test on both and that you provide space for both.
