I am on a Mac running Yosemite, has anyone else run into creating a new document, creating a box with either box tool and not being able to select a color in the swatches palette to fill the box?
With the box selected open the Color panel along with the Swatches panel and make sure you are applying a fill (not a stroke) color and the tint is set to 100%. Also check the Object Style panel and make sure there's not a style applied that would change the fill transparency or fill tint—set the style to [None]
I have two monitors, I had to move the swatches palette to my main computer screen and was then able to select the swatch. Before it was in essence trying to grab and drag the color to the box versus just selecting the color. Issue resolved. thanks
