I am experiencing a loss of function with AC11 and my new mactel 15. After using the software for a few minutes the stretch lines vanish when I zoom in . I also loose the stretch line when using any tool. When drawing a line, for example all you see is the cursor, no start point, no stretch, no indication that you are doing any action at all, but when you click the line materializes.
Has anyone experienced this. The file works on PC.
