For future searching purposes, here is the full text of my response on LAVA, along with the attached VI:
"I believe if you put two '\r\n' characters before and after a given sentence/paragraph, that will cause the paragraph to word wrap. You can try it in your VI by going to Description and Tip and pressing Enter twice before your paragraph, and after your paragraph. I have attached a VI that contains your Numeric control with the context help wrapping appropriately after making this change. If you are changing the description programatically, just convert single \r\n characters into \r\n\r\n. I noticed in your control's context help you just have \n characters, so if you're updating the context help programmatically, you would probably want to write some code that searches for \n before and after text and replaces it with \r\n\r\n."
