I just tried to subscribe to the OS2World News newsletter and when I clicked on "save", I was prompted for the "Joomla Administrator" username and password twice. When I killed both windows, right above the small window that had the information for the newsletters was "ok", just like that.
Just thought I'd let you know.

Ok, thanks I will check that out to see what it is.
Can't really say that I managed to figure out anything regarding this issue, but if any more has the same problem/issue - please report it to us.
