Every once in a while, when using an app, I get a message about WebDev concerning .Mac and iDisk, and asking for a user name and password. I simply click cancel, and it goes away. Unfortunately, I did not write down the whole message when I last saw it, and I don[t know how to deliberately bring it up. Can anyone help without knowing the entire message? The last time it happened was when I hit the "scan" button on my scanner.
