I have a blackberry curve(8330), and when I go to the "media" section on my phone, it says"scanning" at the bottom of the screen. And when I view my pictures, ring tones, etc. it has a white bar at the bottom of the screen. I don't know what this is, possibly you could help me with answering these questions.

-Why does it do that?
-How can I fix it?

-Does it effect anything?
