To be sure I'm understanding your issue -
In family view, can you drag the window at all? There are 2 ways to move around, one by dragging the entire screen with your mouse or the other by using the mini-window at the bottom left of the screen.
Can you click on any "View his/her family tree" boxes? At the top left of most/many people in your tree, 2 little boxes. See screenshot.
In pedigree view, can you click on any green arrows to see an earlier generation?
