Why does my Party client restart every time I close it???

Alright, this has gone on long enough (e.g. a couple weeks). EVERY single time i close my Party client, it automatically re-opens itself. It's just a minor annoyance to close it again, but an annoyance nonetheless.
(What's strange, i guess, is that it only does this one...e.g. it will not re-open itself AGAIN once I close it for the second time).
