Used to be good. Unusable with El Capitain

I used to love this app and it worked great, until I updated the OSX to El Capitain. Now it freezes whenever I click on the menu bar icon, so I have to refresh the window every single time. When typing a message, it constantly freezes until refreshed. Very frustrating to the point of being unusable! PLEASE FIX IT!!!
