OpenPGP -> Set time for passphrase in thunderbird

[Mati]

Hi there,

i have thunderbird + openpgp running and it works. However, i get asked every time i click on a encrypted mail to insert my passphrase. I would like to let the system remember the passphrase. There is an option where i can set the minutes but it does complain with the output

"Your system uses a special tool for managing your passphrase such as gnome-keyring or seahorse-agent. Unfortunately, OpenPGP can not control the active time for these tools. Therefore, the changes for GnuPG will be ignoredt".

What is the problem and how can i set the time correctly?

Thanks

EDIT: The windows showing the error message comes from pinentry. So i assume it might have something with this.

Try to set up a GPG Agent.
