If you encounter an Excel General Protection Fault ("Illegal operation" stuff) then the file in used is not marked "closed" by Excel/Windows. Restarting Excel will only permit read-only access to this file. Restarting Windows usually sorts out the problem.
If it doesn't, open the file as read-only and save it with another name. If you can write after that, delete the original file and rename new file back to the original file name. More.
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.
