DNS Zone problems - Adding new zone & subdomain conflicts

[Nuxwin]

I've received your PM but, I prefer answer to you here.

The current manual DNS feature is unworkable due to several bugs and bad implementation. Several bugs exists (included the bugs described in your post). It's more easy to rewrite this feature from scratch instead to try to fix a bad implementation of it. So, I can't provide any fix for the current implementation because I've not fixed it. I've rewritten all this feature from scratch. New implementation will be introduced with ispCP version 1.0.6.
