I have a problem with the StackPanel.
In code like this:
<ribbon:StackPanel Name="NavigationPanel1" ItemVariantBehavior="LargeThenMediumWhenMedium" MinHeight="72" Margin="0,0,0,0">
<ribbon:Button Name="BtnPause" Command="app:ProjectCommands.Pause"/>
<ribbon:Button Name="BtnPlay" Command="app:ProjectCommands.Play"/>
<ribbon:Button Name="BtnPrevious" Command="app:ProjectCommands.Previous"/>
<ribbon:Button Name="BtnNext" Command="app:ProjectCommands.Next"/>
</ribbon:StackPanel>
only the first 3 Buttons are displayed - in the application as well as the Visual Studio XAML renderer.
It doesn't look like the BtNext itself is the problem, rearranging the order will still show only the first 3 buttons.
Given the version is somewhat "old", is this a common problem ?
