For the last 10 days or so, I have had a problem with the background color of my board using Safari. The board displays a white background and it doesn't show the changes I apply to it. The problem appears only with color changing : I can use photos and change them with no problem. Also, if I attempt to change the color in Safari, Safari doesn't display the change, but the change gets applied, as I can see it with other browsers. As a matter of fact, I don't have that problem with Firefox.
