Great Before The Recent Update

The app was great, but since this recent update, it’s crashes at least 4 to 5 times a day. Hope this gets fixed soon, because it’s such a great app to use.

Constant crashes

Same experience as the other two Jan 2016 reviews; program had been working reliably for years, now it crashes constantly.

Crashes every five seconds.

I’ve used trillian for a few years now and love the app, but ever since the newest update it crashes every time you send a message! frustrating!
