MT4 authentication problem

[intellagent]

Hi,

I would like to prevent that after restarting the MT4 the user will be able to connect to the previously connected account in spite of that in the login window the "Save account information" and in the server options window the "Keep personal settings and data at startup" are klicked on. I mean,  what do I need to delete or modify programmatically  to achieve this?  After restarting the MT4 should always request the login password.

Thanks,

Janos
