Shows Calendar *and* Mail in the same screen Version-Release number of selected component (if applicable): thunderbird-2.0.0.12-1.fc8 How reproducible: Always Steps to Reproduce: 1. Install Thunderbird 2. Install lastest stable version of the Lightning (0.8) extension from addons.mozilla.org Actual Results: User interface displays incorrectly. Shows Calendar *and* Mail in the same screen. Expected Results: It should show only mail at startup and if you click the *calendar* button then show only calendar events Additional info: Previous version 0.7 (which is also packaged in Fedora's repositories) works fine. This also affects another extension called "Provider for Google Calendar". The latest version 0.4 doesn't work with lightning 0.7, but only with version 0.8, which is misbehaving.
