In the past, when I had replies on emails I sent, they always came back as a separate email even though the subject line was the same (since it's a reply). This was with my old email server that was a POP3 setup. Anyway, when I created a POP3 Gmail account, now I noticed that the emails that are a reply get stacked like subdirectories in your filing system. That is, my original message is the first tab, then each subsequent reply is in a new tab so I could have 5 or more stacked tabs. The problem I have is that even though the latest reply might be the newest in date, when I'm in the main email menu showing all the emails I've received, this particular email is at the top of the list because the latest reply is the newest email, however the original date stamp is showing when I created that email rather than the date stamp of the newest reply.

Is there a way in the settings or something to have each reply as a separate email like I did with my old server? Or is this some kind of quirk because of the way Gmail does POP3? The reason I opted for POP3 is because I wanted the emails stored locally on my PC and I could delete all emails from the Gmail server rather than using the synchronizing method of IMAP where all my PCs would have the same emails (using POP3 I could have different emails stored on each PC as I could delete some on one PC while having them exist on another one). Thanks in advance for any suggestions you may offer!
