I use TB portable. Recently, it seems that if I sent an emal from a FireFox link, the Compose window stays open and shows 100% sent. The message is in the Sent folder, but the Compose window stays active. If I send another email directly from TB, it seems to "flush" it through.
I've been experimenting with a suite of Open Source, Portable Apps on a flashdrive. Sometimes I move them to a PC, run them, then move them back. Then maybe to another PC. This open Compose window has happened rather recently. I can't link it to any specific changes.
Thanks, I've used these forums alot to get me going on this. I'm sticking with it and learning alot.
