enter password for default keyring to unlock

["Dave Burns" <tburns hawaii edu>]

I just installed fc9. I never knowingly set any password other than my
login password and root password. But ever since I got wireless
working when I log in I get a dialog:

"enter password for default keyring to unlock
The application 'NetworkManager Applet'
wants access to the default keyring but it is locked"

I enter the only pasword I know of, but the dialog pops back up again.

How do I reset this or get rid of it? What do I re-install?

I googled the dialog message, but there are a million hits explaining
how to get the dialog to never show up assuming you know the password
of the default keyring, which I apparently do not. How did this
password get set without me ever even knowing it existed?

Thanks in advance,
Dave
