I had created several drawings on an older computer and now I have updated to a newer computer. The drawings on the old computer fit on the screen and I could zoom in and out just fine. On the new computer, the drawings display like they are zoomed to the max to the point I can only view small parts of them. When I try and zoom them down to view the whole drawing it just dissapears from the screen. Any help on fixing this problem would be greatly appreciated.
