Crappy User Interface

I go to File > New Account, enter 'gmail.com' as the server (I want to use my Gmail account), I get an error. I can't understand the error, but that's not why the Coccinella UI is crappy. The problem is that I can't close the error dialog. I click "OK" on the error box and nothing happens. As it turns out, I have to FIRST close the previous dialog ("New Account") and THEN I can close the error. This is completely backwards and idiotic.
