Disable locking option does not always work

Hi

I installed Teamviewer on a VirtualMachine and it works fine so far. The only problem I have:

On the user side I set the option "always lock client on exit" to "never".

On the client side i disabled the option in actions menu - lock - lock on exit.

After a reboot of the client, when I login and exit, the client is locked again. Only when I check and uncheck the actions - lock - lock on exit option it works. Is there any solution for this ? After that, when I log in it stays unlocked for a short period of time.

thanks

regards

Erich
