Andrew after not much luck from 1password, I thought it through and decided to completely uninstall 1p and reinstall. This seemed to do the trick. Hazel now automatically finds the 1p data at `/Users/myname/Dropbox/1Password/1Password.agilekeychain`.
Can I just say how impressed by how quickly and professionally you replied to my cry for help. Even Alfred himself would have been impressed. Thanks.
Now I just need to start learning how to use all its capabilities and start saving time!
