MacOS X Lion and the restore function

Hello,

I don't know you but I don't like my browser to restore the last opened tabs...
same for preview!

good news, you can revert it.
open the terminal and type:

defaults write com.apple.Safari ApplePersistenceIgnoreState YES
defaults write com.apple.Preview ApplePersistenceIgnoreState YES

and that's like before, the "good old time" :-)
