Motorola Adventure V750

I have an issue with the Text Messaging part of the phone. About once a day I'll go to text message and the phone will SLOWWW down. It will be 3-4 words behind what I am texting when normally it keeps up fine. Reseating the battery sometimes helps. Call to motorola support was about useless. The foreign lady kept saying "it is a new phone sir, give it a chance" and "that is normal" and finally said something about tranferring me to software to get an update. There is no new software update for this phone. Anyone else have this prob?
