I have mine start via task scheduler and I've noticed recently that it starts in a window instead of minimized, and that I can't close/minimize it normally. I've tried resetting to default and messing around with the settings but nothing has worked. It appears to be (for me at least) related to the setting "Task Bar" which is active but grayed out. Disabling it makes the program function as normal, but on reboot it's right back to being set to active. Setting the config to read-only results in the config file showing the setting as disabled, but it's still active in the program.
