Jon Udell's how-to-publish series; Sunbird flakiness

Jon Udell recently published a series of blog posts on how to publish your calendar on the Web for free. They're useful tutorials. So far, he's covered Outlook 2007, Google Calendar and Apple iCal. I guess I should do the Sunbird tutorial.

Does anyone else find Sunbird itself a bit flaky, though? I've seen some strange things...entries that don't show up until later, and then are hard to delete, unless you quit Sunbird and restart.
