I have Thunderbird in classic view. So catalogs on the left and list of inbox on the right and below the list the view of the mail's content in a preview. Every time I start Thunderbird, the inbox appears in the list. I have sorted that the latest email in the inbox is last in the list. But it doesn't show the last email; it shows a bit up in the list. The reason is that the preview surface COVER the most recent emails in the list (as an overlay and therefore hiding the list). Annoying! If I select another directory on the left and then select the inbox directory again, then the latest mail IS visible in the list because the preview area is now UNDER the list, not covering it. It's been like this for months, are both users and developers blind who haven't seen this problem?
