what are you doing to your BB? :P
For the Content protection, just go under Options>Security>General>Disable the Content Protection, Content Compression, and I set include the address book to No also.
That made it go away on mine. As for your other issue I'm not sure. BBM is a little flakey sometimes. Has some weird quirks to it. If it happens again then maybe it might be an issue but most days it's just dumb.
