I have a problem with adding other accounts on Adium. Now I'm using with MSN account and it seems to work fine. But when I tried to add an account for GoogleTalk (and others too) I'm not getting it work. When I click the plus button on Adium's accounts part it just opens page with what seems to be a box where to write a password but all that is visible only half way. And then there's the button to register the new account.
I tried to look for the answer from the trac page (or whatever it was) and I have the newest version of Adium X 1.2.1.
In what language are you running Adium? (This is likely a problem with your translation - the translator for your language didn't properly update the accounts configuration interface files).
I apologize for asking probably stupid questions, but how do I run Adium in English? I didn't find anything like that from the preferences and when I originally installed Adium it used Finnish automatically.
Set your computer to prefer English in System Preferences -> International by dragging English to the top of the list, then run Adium. You can set it back after you've configured your account. (The problem, by the way, is fixed for Adium 1.2.2).
