When I download an attachment on the Playbook, the message which contains the attachment changes from "read" to "unread." I'm not quite sure whether this is a bug or a feature, and if the latter, what the point of it is. Anyone else noticed this? Using BB on corporate BES system, if that's relevant.
It does this even on my 9700, I think it's intentional, a way to tell you the download is complete if you've gone and switched to other apps and stuff during the download.
