Comment 6 for bug 372230

Thunderbird Version 2.0.0.21 (Build 20090409)
Lightning Version 0.9 (Build 2008091718)

To Reproduce:

1. Install Lightning
2. Open Thunderbird
3. Click on "Calendar" in the bottom left corner of the window
4. Right click into the "Calendar" pane just below the small month-view.

What strikes me, is that not a single calendar is shown. Normally Lightning/Sunbird refuses to delete the calendar if it's the only one left IIRC. Right now, as seen in my screenshot, the main view is plain white. It does not show any grid as you would expect.

I installed Sunbird earlier today, and there it seems fine. As the only calendar I am using is a remote calendar (using WCAP), I can easily switch between Sunbird and Thunderbird.

I'm beginning to suspect that it may be a problem in a configuration file. I'll dig around a bit and see what I can find.
