Highlight and line doesn't show in Matching Type

Dwayne said: you could open the "trivantis-match.js" file and change the color to something that does show up on your background. default for the color is "0000FF". maybe a nice red instead?

No, I don't think that will work... The problem isn't one of contrast, it's that Lectora will not draw the lines on top of another object, even a background one. When there's a background, the lines are there, you just can't see them because they're hiding behind the background object.
