Hi
I have reproduced the problem. Have added some details below but I think it is a jComments 'challenge' as they appear to heve picked up or constructed the wrong return links in the email.
{In process of looking at this I set jComments "Enable quick moderation" to Yes. afterwards I set it back to No. But it still keeps saying will publish after moderation!!! The email that is sent is correct as it has no Quick Moderation links}
When one asks for quick moderation by setting jComments "Enable quick moderation" to Yes then for publish, and also for delete and unpublish, all proceeds nicely and an email like below is sent - the italic bits have been added to refer to below, and the parts in blue are the links.

a second test comment
Quick moderation Publish | Delete Note B
Note A Link generated is below (I have changed the actual site to mysite.com). This is the link which would, I believe, be used as the return link when jComments have completed any 'action'
<a href="http://www.mysite.com/list-all-a-categories?view=viewdownload&catid=16&cid=96#comment-8" target="_blank">downloadtopA-3</a>
Note B The links generated for Quick Moderation are below. These are the jComments action links and it is evident that the actions are completed but it is the return link that is incorrect.
<a href="http://www.mysite.com/component/jcomments/publish/8/447e2e616f65243b9d927df1526a4d6b" title="Publish" target="_blank">Publish</a>
<a href="http://www.mysite.com/component/jcomments/delete/8/3aba36d324676e2f879d76edf957ff36" title="Delete" target="_blank">Delete</a>
All three links above finally result in the 404 error. The actual link to the relevant Details page is
http://www.mysite.com/downloads/download/16-topa/96-downloadtopa-3
Note: The email sent for Quick Moderation could be actioned several hours later. It could be in an area that needs login by a specific User Group. If I use the correct link as immediately above it takes me to the login page and after logging in as appropriate it proceeds correctly to the relevant download detail page.
