Solved email no longer chronological-but in orig expanding box

I usually am able to sort my email chronologically, so that the latest emails are on top.
But now if an email comes in that was a response or reply to an older mail it is automatically filed under the original email. A little white box is created that has a blue plus sign. If I expand that blue+ sign I can find the responses and replies.

A problem Here is an example: I will go to recieve email and I will be told that I am recieivng 3 emails, but none are visible, so I have to go looking thru the boxes. Some of my emails could have 20 different reply emails, and they could be from months ago. this is causing me to miss or overlook emails.
Is this a result of an update or have I changed a default?
Thanks for help.

Welcome
If you are using windows live mail. It is time to update to Windows Live Mail 2011.
This may be the easiest solution.

Also try this
Click on view. Take a look at the different column headings. Maybe you are sorting to one of those.

I found the answer

Go to : View> Current View> and make sure “ group messages by current conversation” and make sure this is not checked !”

Glad that it worked out I had a feeling that the answer was in view.
Happy Holidays Mary.
