Notification Box for Texts

[M2Iceman]

I had to do a factory reset on my wife's Hero due to not receiving MMS or texts. Since I tried everything to help fix it, the last resort was a complete wipe.

My wife has an issue with when a text message is received and the phone is locked and in standby, part of the message is shown at the bottom of the screen and a box is in the middle of the screen until you unlock and clear. She doesnt like the messages to show because of work and having gone through the phone, I cant find a setting to clear it. Is this an issue with Sense UI or did I overlook a setting to hide the notification?
