Originally written February 17, 2007, I've upgraded this to use the Beta 1 control. There were no surprises with this, just plumbing and normal changes such as removing "javascript:", or modifying args.x as I've discussed in previous conversions.
Some of the issues are still in Beta 1 apparently, such as the ability to take a mouse hit on a Glyph. If you look at the exposed xaml, the checkbox canvas contains the MouseLeftButtonDown. That canvas includes the glyph and the text, yet only the text launches the code.
