keeps crashing

update to yosemite on brand new macbook pro and everytime i try to copy and paste from a pdf or pages import it crashes. It can be a paragraph or a page, sometimes just a sentence and it just crashes and gives a error message saying that it closed. Used to be able to copy an entire 90 pages and paste into program. I have to import exact word for word from government and private contracts and then we add our portion to each area to make sure we dont leave anything out. This bug is very very frustrating and the crashes are unwelcomed.
