Modal window not closing?

I believe you are using the RunLoop in an incorrect manner. The RunLoop is a loop which manages display and interaction of the GUI widgets within your App, if you stop the main RunLoop your App will stop updating.

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.
