Are you sure when closing main game window (Mac version)

Please put an "are you sure" confirmation to stop the game quitting when the main window is closed on the Mac version. I still can't get used to the windozey close buttons on the right side of windows, often when i have lots of game windows open I absent mindedly click on the close button that I "am used" to seeing on the Mac. ie: the red one at the top left of the main window. Oops! Quit! ... much swearing ...

lol are you kidding me? Please Linden Lab...protect us from that mean 'X'....I so didn't want to click it...

actually you put it quite eloquently, i wish I'd said that.
