settings not use first time after set it …

Hi,

I have write a program launcher plugin adapted to a NAS environment …
to be able to start Chrome (with URL or not, in App mode or not), firefox, any NAS HDMI interface application from Kodi …

All seems to work as expected (configure, run, edit, delete, etc.) with only one problem
I have some settings (boolean) … when I change this settings (right click on addon icon or from addon menu), the setting is change (when I read the settings.xml in the addon_data of the user) … but
If I start (execute) the addon the changed settings is not used … but if I stop it and restart it … changed settings is apply and use …

I have not discover a sort of refresh in addon Python interface … so I don’t know why …

Do you have any idea … or advice to search …

Addons is write in Python, run as well (except the small difficulty) under Kodi 17.1

Philippe.
