Hi. New here and have reviewed open topics quickly but no joy.
I have ThunderbirdPortable working nicely on both GMail and another (Shaw) webmail account, loaded on a large capacity brandname USB thumb/flash drive.
After finishing my email work, and Closing/Exiting TBP, I cannot safely eject my USB drive ('busy', close open apps, etc.).
If I am working in the PortableApps alone (including installs/updates to apps) without opening and closing TBP, I can safely eject my USB drive ('safe to eject hardware').
This occurs both on my managed workstation Windows 7 and on my home laptop Windows 8.1, on any USB port (pretty sure the workstation is at a glorious 1.1, my laptop has both 2.0 and 3.0 ports).
I have searched the web extensively and am at a loss, seems to be only me (or I'm not using the right search terms).
Any suggestions?
