Recently installed on a (W10, 64bit) computer. I found that entities (inserted images or drawing objects) in modelspace don't show through the viewport in paperspace . When the cursor is put into the viewport ("MS"), the inserted image shows if the cursor moves over it; likewise, the selection vertices of drawing objects show when the cursor moves over them. However, everything shows in the sheet print-out. A friend has the same problem with his recently installed DS 2018 on a different computer. What's causing the problem?
