Alt-Tab was the exact reason why I downloaded the Windower for FFXI. It's absurd to think that in 2011 there are still games that don't allow this. Alt-Tab definitely needs to be implemented. It doesn't stop botting, and encourages otherwise rule abiding legitimate players to break the rules. You can play the game in windowed mode already! The only people you hinder now are your paying customers. What logical reason could there still be to not allow this?
