I am using Zindus to sync my Google contacts with Thunderbird. It works great, but I noticed that some addresses are not synched ?

This might be caused by a bug / missing feature in Zindus whereby it does NOT sync mailgroups. In fact, it even skips the contacts in the groups too. Removing the groups will solve the issue.
