Detect MathZones in PowerPoint 2010
In PowerPoint 2010 Math Zones were introduced. A math zone is a text range within which math typography rules apply. The MathZones object was meant to be a way to detect such but sadly it's broken. It will always return 1 for any textbox with text. In 2013 it works correctly. So I had to come up with a hack to detect math zones. It works in almost all cases where you enter a proper equation. It relies on the fact that with math typography the texteffect property will return incorrect text to match against the value returned by the text range.
