I have just installed the new 2.0.4506.10553 64bits jitsi on openSUSE 12.2x64 . There is an issue with the accept-reject dialogue window on incoming calls. It disappears in a fraction of a second and that makes impossible taking the call. The information window stays until be clicked. It is the same for audio and video calls. The previous 1.1.xx version hasn't such behaviour .
