Installed UI Tools v1.4.1.74 from VIPM. Although the examples are listed in NI Example Finder, the examples appear to be missing. Clicking on any listed example produces and error saying the file could not be found.
Also, as I was poking around, I did find a bug with the flowing of text when creating a message box. It seems that the Message string input must contain at least one CR for it to display the scroll bar properly.
