Thanks for all your help. I have a few outstanding issues that I can not solve.
1. Zimlets do not work, despite them being enabled, active, and the COS assigned to the user permits their use. (i.e. When I move my mouse over a URL nothing happens).
2. Distribution lists, despite being active, the recipients in the distribution list do not receive any emails. I do not receive any return emails notifying of an error.
Is there anything I can attach to this post that can help you diagnose this problem?
Thanks again for all your help and a great product.
