I use CS6 on Windows 7.
My default interface preference was set to Live Screen Drawing: Delayed. I tried changing from that, it was the same deal. I have noticed though, that performance is a lot slower when Display Performance under Object.
For the extra lines showing up, I can't seem to find that same problem again, so I can't use a screenshot.
SRiegal, I don't get what you mean by copying the colors. If you say that InDesign cannot copy the color of vector graphics, then how can I recreate them not knowing the exact values?
