It may be that the bug is somewhere else, with some other class that is using your view without holding a reference to it. If you don't invalidate your timer than it will have a reference to your view forever, potentially extending its lifespan and masking memory management bugs elsewhere in your code.
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.
