possible bug:
if you have two chat window's, they echo text from the other window.
it is not specifically text input - you can remove the input and come up with the same echo effect by using textlist.add(text).
i havent spent a ton of time trying to figure out what is going on... but it appears that it is something with UITextList.
this effect can be reproduced by copy/pasting the window from example 12. the only change in the screenshot is that i unchecked "dummy data".
