Password cache trouble

My iSeries Password was recently change on both iSeries systems I have
defined to WDSc.

One of them isn't giving me any problem.  But with the other one WDSc always
pop up a password error box.  I typed in the new password and marked "save
password" multiple times but it has had no effect.

I've also made changes in the Preferences-->Remote Systems-->Passwords.
Even going so far as to delete the entry for the problem system.  Nothing
has fixed the problem.

It's particularly frustrating since the error dialog pops up behind
everything else so I don't know it's there till I go thru and minimize
everything.

Should I try deleting the remote system and recreated it or is there
something less drastic?

Thanks,
Charles
