OK. This has gotten quite frustrating. I am reaching for the button to close a sub-screen and I unconsciously reach for and click on the big red "X" at the top right of the main screen. AAARRRGGG. I didn't really want to exit the game!!!! Especially without saving!! And, why, oh why, do I keep on doing that???
I do believe GC1 and GC2 intercepted this process and asked if I really wanted to quit. And I have seen many other games that had the same protection. This really needs to be an industry standard for ALL games.
