Any controller that I open with TTNavigator results in a blank view?

The problem arisen because I forgot to remove the window outlet from my App Delegate (both in the interface declaration and in the XIB file). Since TTNavigator uses his own window to present view controllers (unless specified explicitly), creating another window can result in weird behaviors. Apparently, this didn't give any issues with the old Three20 (or maybe Xcode) so I didn't even notice.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
