Absolutely great news! I've been waiting an age for this release, and I hope it was worth the wait (I'm sure it is). Thanks to anyone and everyone who helped with the release.

I yearn for the day when all these apps run off xulrunner...

....but the annoncement links to a _web_ page which has a download link for Lightning. Click this link, the XPI downloads and tells you it's incompatible with Firefox.

User friendly???

I have to agree with the "user friendly" comment. Even though I know the extension is for Thunderbird, my instinctive reaction is to click on the XPI link to install. A popup box saying "This extension is intended for Thunderbird" or similar would be more user friendly imo.

I just installed it and it didn't give any trouble, it even picked up automatically the old .ics I had when I was using the Calendar extension a year ago.

My problem is with the little calendar that appears on the left under the accounts tree. Is there any way of getting rid of this. It is really in the way. I don't mind the agenda or todo list, but the small calendar is an annoyance, taking up so much space.

I use Windows XP Pro. Sunbird 0.3 does not run on my computer, even in safe mode. I get the hourglass for a couple of seconds, no matter which way I try to run Sunbird, then nothing more happens. Sunbird 0.2 ran just fine - and, in fact, now that I have uninstalled Sunbird 0.3 and re-installed Sunbird 0.2, Sunbird 0.2 runs just fine again.

I note in the Sunbird 0.3 release notes that there is a comment about the potential for problems from Add-ons - and that if Sunbird 0.3 does not want to start, then one should run it in Safe Mode (which is available from the All Programs menu), find out what the source of the problem is, get rid of that, and then Sunbird should run in normal mode. In my case, that does not work because Sunbird won't start even in safe mode. The No Extensions option also does not start it.

I will note that the only extension that I remember installing in Sunbird 0.2 (which is the first version of Sunbird that I tried) is an extension that handles holidays - but then I also realized, once I had it installed, that I do not know how to get rid of it again if I want a different holiday file (I did look - found nothing). Can it be that Sunbird 0.3 is dying from something as simple as that? Even if so, how do I get rid of it? I went looking, even now again once I had Sunbird 0.2 installed again, and found no way to get rid of it - so I can't even try that and see if it will make a difference.

I will note that I also installed Lightning 0.3 in Thunderbird. It works fine. (I never did install Lightning 0.2 - since it was not really complete enough yet; I only installed Sunbird at the time to find out how it looks and nominally functions.) Now that both Lightning and Sunbird are truly functional, I wanted to check them both out. Is there maybe some interference from Lightning installed in Thunderbird? I did disable it (and then restarted Thunderbird) to see if that would make a difference - but it didn't.

Now I have Lightning 0.3 installed in Thunderbird and operating just fine (I enabled it again) and Sunbird 0.2 installed and operating just fine (both are running at the same time).

Note: I did power down and power up my computer at each important stage of the set of attempts that I just described - which also made no difference.

OK, I admit Sunbird ain't perfect but, hey at 0.3 its still a nestling. Give it a chance! If the Sunbird devs are reading this I like it,keep up the good work!

I, too, had problems when installing 0.3 on my winxphome computer with sunbird 0.2 on it. However, I finally uninstalled the 0.3 version, reinstalled the 0.2 version (which worked then) and then uninstalled 0.2. Then I reinstalled 0.3 and it worked fine. I then had to import my ics file from the document & settings folders to see my old calendar events. Seems to work fine. Stan
