MMS/SMS app returns to "wrong" message

[froggersloth]

So, a strange problem. I get text messages from my bank for various reasons. I also get text messages from folks I know. So, let's say I have a conversation via text and then hit "home". Then, I decide to re-read a text message. I hold the "home" button and select the texting app from the 8-app popup panel. For some reason, it *always* enters me into the text messages from my bank. Not the listing of conversations, not the most-recently read... always the bank messages, even though there are no waiting messages for me there. Any idea what's up? What determines which messages load, and how do I change it?
