What is your current problem with MUI39R3? And how VP fixes it?! It can only effect the window OS gadgets.
And it would be easier if you can post the bugtracker number that refers to your original post.
To everybody else:
Are you going to miss the XEN button look ?
Actually the 3D button frame with shiftable image and text when you press it ?
This original MUI feature has been removed due to a bug in original code and how it was managed.
