When I try texting certain people from my HTC Thunderbolt, the text field already has a partial text message that was part of a draft or failed message from many days ago. I can't get this message to clear so that I have a blank text field when I go to send a message. I can't stand having to delete this text everytime I want to send a new message. Can anyone tell me how to clear this old text for good. I've tried restarging the phone and sending the text many times to no avail.
