WPF spell check for Uppercase notes

I am wondering if anyone knows if WPF will do spell checking on fully uppercased notes?

while i do have spellcheck enabled:

    <TextBox x:Name="inputBox" 
			 AcceptsReturn="True" 
			 VerticalScrollBarVisibility="Auto"
                          Height="100" 
			 TextWrapping="Wrap"
			 SpellCheck.IsEnabled="True"/>

it only works on lowercased words.
