AT&T ATRIX 2 - Bluetooth File Transfer Problem

[birmanfan]

I hate to ask what sounds like such a stupid question, but what is the secret to successfully transferring files with Bluetooth on the Atrix 2? I have done this with so many other cell phones with no problem, but trying to send files to the Atrix 2 ends with a message on the Atrix saying the file transfer was unsuccessful. The sending phone says that the file was rejected. I get the notification from the Atrix and my Krzr that the phones are connected. The Krzr shows that the file is being copied. Then after about a minute, I get the message that the transfer was rejected. I am guessing I need to do something on the Atrix 2, but I have no idea what. Any suggestions would be greatly appreciated!
