I did install Clipboard Manager, and that ended the issue with my phone sending text messages with the text stored in the built-in clipboard. Unfortunately I broke that phone and when I received my replacement I had the same issue come up again, so I know this is a recurring problem with the Droid Bionic. The strange thing is, on my end the text looks normal, but the person who receives it has an entirely different message then what shows as sent on my phone, so I had no way of knowing what the other person was seeing or how often this happened (a major issue when you use your phone for work!). The guys in the store just scratched their heads over it.
