When I change colors of the grid lines in the document properties window, all the lines on the whole page change to the color I pick for the major grid lines; and no lines change color when I change "Grid line color". The program thinks all the lines are Major; even though I have the number "5" in the box - "Major grid line every:" When I change that number, the boxes just change sizes without indicating a change every 5th line etc.
What is the problem here?

Thank you.
Terry
