A few quick answers:
Yes, of course a free upgrade 🙂
The proper behavior is for DPS to relaunch in exactly the same state as you left it. So if you have the GUI (console in your words) open when you shut down your computer, it should reappear when you start it again. And if it was minimized to the system tray when you shut down your machine, it should be in the sys tray when you start it again. The problem is that DPS is not saving the settings properly to the registry when the machine is shut down. If you quit DPS manually, the settings will be saved. This is a bug and will be fixed in the next release.
