I've encountered this problem 3 times so far and I'm wondering how to fix it. It goes as follows. My spaces are: 1. iTunes, Finder, System Preferences, etc. 2. Chrome 3. Skype, GChat, etc. 4. Safari Normally it works fine, switching to the right goes to the next one. When I quit out of any application, however, the order switches and space 3 moves to the left of space 2 so the order is now 1>3>2>4. I know it's not a huge deal but how do I fix this? On another note, how long is the battery life on a 15 inch i7 2.0 gHz Macbook Pro? Mine seems to last for only 2 hours even with only 3 applications open.
