Heming Zhu, thank you so much! That worked with just a little change to make 'isEditable' false instead of true. Luckily I was able to figure out exactly where those lines of code needed to go.
A text area now displays for existing points when you click on them which is great. A text area does not display when a user is creating a new point. While it would be great to have a text area there too, I'm just so thrill to have everything working that I may just leave well enough along.
Derek Swingley, thank you as well! Your method on stack exchange worked as well - exactly as Heming's method did, only I didn't have to change 'isEditable' to false... it was already done for me. As I mentioned earlier, I'll leave well enough alone and not worry about how the info window appears when creating a new point. If it's an easy fix, please let me know.
