I have a problem with the preview mode in Illustrator CC. It doesn't show live the modifications i do in a file until i move or zoom in the canvas. For example, if i try to move a figure it doesn't show the figure's new position until i move the canvas. The same issue appears if i try to type, it doesn't show what i've typed til i move or zoom in the canvas.
And also it doesn't let me quit until i've saved the changes, so i have to force it…
Thanks in advance.
