I also found out that after going from BB v0.9 to v1.0, my music app fast scroll function seems a bit tweaked.
Like when you're in any one of the lists in the music app (i.e. "Artists," "Albums," "Songs," or "Playlists") and you flick up or down the list, a gray square scroll bar to the right becomes visible and you can press and hold that to scroll too.
When I do that, typically the letter of the section of the list you're at pops up. Like if you're at a point in the list with songs that begins with "A", a letter "A" would usually pop up when you're fast scrolling.
Well, for some reason, mine doesn't pop up the correct letter anymore. In fact, it jumps to different parts of the alphabet, and some were even repeated in caps or lower case!
This doesn't happen in the phone book "Contacts" list though.
Anyone have this same problem?
