BB Bold :: Unopened SMS/MMS Icon, How To Get Rid Of It

I upgraded my Bold 9000 to v5.0.0.592 (Bundle 1004, Platform 5.2.0.57) to see if that would fix a power drain problem. Since then I've had an icon indicating an unopened SMS or MMS, but I can't find this phantom message to open it.Settings:Messages, Menu, Options, Inbox Settings, Email Accounts: all are ticked. Other Messages Types: SMS And MMS is not ticked.

Messages, Menu, Options, General Settings, Display Message Count: Unread. Display New Message Indicator: Yes.From the desktop, the SMS and MMS application shows the following text at the bottom: "(1) SMS And MMS", but when I go in, there are no unopened (yellow speech bubble) messages, only 1 opened (white speech bubble) SMS (it's in the SMS SIM Card Inbox). If I choose Menu, Mark Unopened on that SMS, the icon indicates 2 unopened SMS or MMSs; I then open it and the icon shows 1 unopened message; so it's not message.There are no unread messages when doing the following search SMS And MMS, Menu, Search, leaving everything as default except for Show which is changed to Unopened Only, Menu, Search: "Search Results (0), * No Messages *".There are no unread messages when viewing the following folders: MMS Inbox, MMS Outbox, SMS Conversations, SMS Inbox, SMS Outbox, and SMS SIM Card Inbox. I also checked all the other folders, no unopened messages there either. There are also no unread messages at Menu, View Saved Messages.After shut downs or battery pulls, I always also get the white on red asterisk indicating a new unread SMS or MMS. Doing a battery pull while the BB is on doesn't fix it either, nor does rebooting by holding the alt and right shift keys and pressing the del key.Changing the theme doesn't fix it either.Since upgrading didn't fix the power drain problems, and I've read online of others with similar problems since upgrading to 5 (not all of who've been able to fix it), should I downgrade back to 4?
