Hard Disk Monitoring

Hi, I just bought this incredible program, but I'm having difficulty with one setting:

I don't want the main window to display automatically when Windows start, but it's displaying.

Below is my configuration, I thought unchecking both "at start" and "when started" would do. Is there anything else to be configured?

Thanks in advance.

Well, today is behaving corretly, I have done numerous resets and it's not showing the main window at startup.

I havent' changed any settings, wonder why it was like that, just hoping that won't revert back.

The Configuration -> Preferences -> Display main window when started
option controls this behaviour.

I wonder why you encountered troubles: if that option disabled - then the main windows is not displayed on startup.
There is one exception: if you had unregistered (trial) version, then the main window (and a registration reminder) always displayed.
