After quitting the game by any means (pushing the last button* in the main menu or the Download Updates button) does not actually seem to shut the game -down- on my system.
As in: It's still listed in my processes listing twelve hours later.
Worse, it seems that every time I quit (or possibly every time I End Process the Sins of a Solar Empire.exe process) my system starts to slowly grind to a halt.
Very very bad.

*I don't remember the exact name of the button (Quit?) but I don't want to turn the game on again just to find out. I had a mild scare the last time I had to turn the machine off because it came crawling to a halt because of Sins with windows complaining about lost registry entries.
(PS While I don't use Steam's overlay in Sins (yet), I've seen some of the complaints about it and one of the responses about it from Stardock. It's a damn shame you guys won't even consider trying to work out whatever bug is causing problems, whether it's yours or theirs. PC gamers want options and compatibility, not forced restrictions. Besides, it's free advertising for your game, seeing someone on a friends list playing Sins.)
