note about interest not showing is gone from NR logon screen but it just rejected my login attempt and when I retried it failed as I am already logged in!!!
That sometimes happens when (I think) you were previously logged in and the session has not timed out on the server side. At least I think it's a server side issue since manually deleting NR cookies, closing and reopening the browser or trying another browser/PC didn't help.
I have it written down in a spreadsheet. I think it changed to 4.15% pretty early in the year (2nd or 3rd of January). Changed to 4.3% on the 4/4/07 and then to the current 4.5% on the 6/7/07.
