I don't see any code that would prevent the scrollbars from working. I do see a problem that prevents one of the scrollbars from showing up where you expect it (assuming you expect them to appear in the traditional place). Is that what you mean whey you say you want them to "work simultaneously"?
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.
