Security concerns

Trillian requires connecting to your chat server by proxy via a trillian account. This means that this Trillian account doesn’t connect to the server it self, it only connects to the trillian server. The trillian server will then connect to each of your accounts, and it means that the trillian server needs to keep a copy of your passwords.

There’s no way to audity the security or trustworthiness of the trillian proxy servers.

Open app, no windows show up

I open the app and no windows show up. I go to the 'windows' drop down and select contact list, downloads, etc. I click on all avaialble windows and still nothing shows up.

Doesn’t Open

I installed it twice. Nothing happens. Nothing pops up at all. Trillion doesn’t really care about Mac uses like it does about Windows, I know that, but this is kind of ridiculous.
