Two issues:

1. When using Swype, if you have incorrect word in chat box and then select the correct word from the suggested words listed usingGoogle keyboard, even though the entire word is highlighted, it will add to the existing word instead of fixing it

2. When trying to fix a word in the chat, it continues to guess the word, this adding more characters to be deleted. You continually have to backspace until it gives up and you can actually fix it. Very, very annoying.
