Im not getting chat message notifications

I like the idea of this little app very much, and I like how it handles Gmail. I wish I could eliminate the need for iChat by also using it for GoogleTalk, but although I have "New Chat Message" notifications enabled in Growl, no chat notifications are appearing. The advertised GoogleTalk support (the reason for paying $1.99) is obviously quite restricted if you never know when you have incoming chat messages. Hopefully this can be fixed easily.
