This has just come to my notice after many years of using PM.
When using the Message Title Bar option in Advanced Message Options the subject is shown as well as who the message is from.
This is correctly displayed except in the Sent Folder where the From address is still shown. Not really relevant in the sent folder unless it is a reply or forward. But in all cases the address, where shown, is the To address not the From address.
The From address should in all cases be my address as the sender.
Occasionally no From address is quoted and this is usually in a new message with no quotes or forwards.
In other words I send an email To someone and what shows up in the Title Bar is that it is From the intended recipient.
Is this just me or have I stumbled across a minor bug in the Sent folder.
