On the "Remote Addresses" tab in Applications, there is an "Address:" text field, and "Add", "Update" and "Cancel" buttons.

Entering a new address and pressing enter, I would expect this to Add the address. But it doesn't - it actually triggers "Update". The result is very misleading - there is a happy "Update Successful." message at the top, but the IP you just entered hasn't been added.

Pressing enter on the text field should trigger "Add", not "Update".
