In trying to segment a spreadsheet into four sections, I draw a verticle line
from say row 3 Column F, down to row 30 Column F, keeping the line directly
on the graph line and color it Red. I do the same for other sections of my
spreadsheet. It has worked in the past where the lines stay put and are
there perminately.

Now, they dissapear when I move up or down in the spreadsheet. If I move
down 1/2 page and them go back up, one half of the line dissapears?? I did
not change any settings and I cannot figure out what's going on. Any one
have a suggestion.

Thanks.
