Hi I was working on a exam assignment, and suddenly my document reacted weird. After some ctrl - z's I was back at my original document but when I tried to mark and write in my document I couldnt. Now I'm stuck and no matter what I try I can do nothing but watch the document. I'm really stressed as it is soon due and I have worked on it constantly in over a week. If somebody is able to help me that would be awesome
