Lone Vibrating Text Notification

[Googie1130]

I have an unrooted TB and use Handcent for texting. I have it set to vibrate AND give a sound alert for incoming messages. My problem is that for ONE contact only, the alert ONLY vibrates, no sound. That ONE contact happens to be the person I text the most. I have tried deleting the contact, but when I re-enter it, it does the same thing. I have searched high and low to find a setting for this but can't seem to find anything. Any help appreciated.

Strange. What happens if you enter an entirely new contact? Same thing?
