Eris grey envelope with arrow wont go away HELP!!

Ok so this notification just started on my Eris! when I get a message(only text not emails) this grey envelope with a arrow on it comes up in my notifications even after I’ve read and replied to the message its still there until I click it and see the message that ive already replied to. I’ve turned of all settings has far as auto retrieve and text notification but it still comes up! I deleted a bunch of apps thinking maybe one of them was causing this. I called htc they had no answers but to do a hard reset and lose everything not something I want to do! So if ya know something that would help please let me know thanks!

 

The fix!!!!!

Aspotcat can be downloaded from the market it will show you what is running with ur text. found out some weird app was on there but no where to be found in my phone deleted it and problem solved!
