I think I may have found a pair of bugs from the ListView of your Office2007 Themes.,
Windows 7 X64
1) My ListViewItems (stackpanel with an image and textblock inside of) you should not display.
2) There seems to be some form of clickable button on the top from the ListView by using your concept but there is absolutely no button once the concept is removed.
Here would be the XAML for my listbox:
Width="130"
Height="Auto"
Name="lstSections"
SelectionChanged="lstSections_SelectionChanged">
Foreground="#FF0000D5" />
Height="16"
Width="16" />
Foreground="Black"
VerticalAlignment="Center" />
Any help resolving these issues would be appreciated.
