GPG and 2nd Profile

Tried to use ThunderbirdPortable2ndProfile but does not seem to be set up to use the GPG Plugin. Couldn't find GPG and when given path it creates the keyrings and other files under Application Data\gnupg. When exit Thunderbird the gpg-agent.exe and gpg2.exe are left running. On exit the keyrings are left in Application Data\gnupg. Can this problem be verified?

I have not checked but SeamonkeyPortable2ndProfile may have the same problem.

Win XP SP3
Thunderbird 38.6.0
Thunderbird2ndProfile 1.2 (downloaded today)
GPG Plugin Portable 2.0.29
Enigmail 1.8.2

Three tests:

1. with normal Thunderbird Portable:

so OK.

2. with ThunderbirdPortable2ndProfile:

note: under ThunderbirdPortable2ndProfile\Data, ThunderbirdPortable.ini contains lines:

GPGFullPath=G:\PortableApps\ThunderbirdPortable\App\gpg
GPGHomeFullPath=G:\PortableApps\ThunderbirdPortable2ndProfile\Data\gpg

but nothing stored in G:\PortableApps\ThunderbirdPortable2ndProfile\Data\gpg

3. custom built profile using folders and files from ThunderbirdPortable (fresh installation) and ThunderbirdPortable.ini next to ThunderbirdPortable.exe

so OK
