No actual confusion now:  You saw that, undoubtedly, because you are 
using the default Windows XP "Windows XP style" appearance for the OS. 
But I was using the "Windows Class style" appearance.  ProgressIndicator 
takes the form appropriate to the platform which, at least in the case 
of Windows, includes the style (theme, skin) in use.
