Marc, are your familliar with mSafe? I don't know about the other locking apps out there, but when mSafe is running (eg. phone is locked) and an email message comes in the notification screen pops up overtop of the locked screen! So, even if my Treo is locked someone can read my incoming mail. Is this a problem unique to mSafe? If it's further reaching could the Chatter popups be suppressed when the Treo is locked? Thanks,

Dunc
