KG Chart help

[funkymonkey]

Hi, I'm usually pretty good at figuring these things out myself, but I couldn't figure it out in the program or online so I thought I'd see if anyone here knows.

I made a pattern in KG chart, and when I go to print it, it shows a dark grid line every 5 stitches and I'd like it to be every 10. How do I change that?

Second, the multiple pages of the pattern don't show any "greyed out" or overlap rows, is there a way to get it to display these?

Thanks!!
