gpg-agent and --no-grab option on Windows 7 Pro 64bits

Hello,

when I put the “–no-grab” option in the gpg-agent.conf file, the gpg-agent.exe binary won’t launch with the following error:

C:\Program Files (x86)\GNU\GnuPG>gpg-agent.exe
gpg-agent[1076]: C:\Users\nikolaii\AppData\Roaming\gnupg\gpg-agent.conf:3: invalid option

However, this option is present in the help:

C:\Program Files (x86)\GNU\GnuPG>gpg-agent.exe -h
gpg-agent (GnuPG) 2.0.17 (Gpg4win 2.1.0)
libgcrypt 1.4.6

Options:

 --server                     run in server mode (foreground)
 --daemon                     run in daemon mode (background)

-s, --sh sh-style command output
-c, --csh csh-style command output
–options FILE read options from FILE

Please report bugs to http://bugs.gnupg.org.

What’s the problem?

Thanks for your help.

Never mind, I found by myself: the option doesn’t require two hyphens at the beginning, the option thus must be written like this in the configuration file: “no-grab”

However, this option isn’t taken into account by the “pinentry” process, so this isn’t very helpful …
