In TB 148, it indeed starts with Inbox if there is a mail in the Inbox. If the Inbox is empty, it will select the latest read message marked in a subfolder (but: this is true only if the add-on "last selected message" is active).

I cannot reproduce the issue.
Can you please contact me via k-l-p@gmx.de in order to identify the problem?
