There are two possibilities: (1) I don't remember exactly what was there before(2) One of the two network management programs that are running changed something that I don't know about.In my Notification Area there are two programs that seem to be controlling the interfaces, and perhaps causing my problems. They are Network Manager Applet and WICD Network Manager.
Do you remember which one you used? Both can be used, but if you try to use both at the same time you'll have problems. I'd suggest uninstalling one of them, or at the very least make sure that they aren't both trying to control the same interface. Neither will modify /etc/network/interfaces, so just ignore that.
