Of course, Google changes it's rules wihtout further notifications, so, it can happen once every 2 years, few buggs appears. But what...? I've been using this app for the last 3 years and it works great, I don't even think about that. All you have to do is to READ TH MANUAL and do your little home work...

I rve read many negative reports, due to inappropriate behaviour of users...

Thank you to creator!

Sure, this app can get unstable after each update of both google and Thunderbird. But Every time, after a new clean update or re-install of the app, it works great... The developper achieves new working updates. Fresh installation needs couple tries, because there's no manual to make it easy. Perseverance is the key word ! Try all install solution until good result :-)

Just uninstal version 1.0.1 and re install previous version here:https://addons.mozilla.org/fr/thunderbird/addon/4631/versions/
and let's give time for a corrected 1.01(2) version... and do safety copies of google calendar. This issue crashed 50% of my calendar... my fault, I made no safety. And uncross automatic updates!!! Conceptors are not gods, and google can change whatever without telling anyone....
